Are Dreams made of Atoms?

Blank Rascal opens with two questions that sound equally silly: are dreams made of atoms, and are atoms made of dreams? The first answer is yes because everything in the universe is made of atoms. The second answer is no because atoms contain subatomic particles, and those particles lead into a physics that the speaker admits he barely understands. He describes himself as a monkey with a YouTube channel rather than a physicist or a “dreamologist”, then spends the rest of the video pushing a simple question into the gap between physical processes and subjective experience.

Dreams as involuntary worlds

A dream is a succession of images, ideas, emotions and sensations that usually appears involuntarily during sleep. The definition matters because the mind does not choose its nightly films. The source gives the speaker’s estimate that roughly one in forty dreams becomes a nightmare, with the odds changing alongside mental health, then turns to the strange conviction dreams create whilst they happen. A dream can present a landscape or situation that feels entirely convincing even when it collapses as soon as waking begins.

The video gives a compressed account of what happens in sleep. The prefrontal cortex becomes much less active, which helps explain the reduction in logic and critical thought. The brain releases a mixture of dopamine, serotonin and melatonin, while gamma-aminobutyric acid helps keep the body physically still as the eyes move and brain activity changes. The source presents this as a rough explanation rather than a complete account of dreaming.

The purpose of dreams remains open. One evolutionary theory treats threatening dreams as simulations that prepare a person for danger. Repeatedly escaping a monster in sleep might improve a person’s response when a real danger appears. That theory leaves the speaker’s own dream unexplained: he describes having sex with Margaret Thatcher whilst riding a flying pyramid. The example separates the possible function of dreaming from the particular images a dream can assemble. The conscious person may reject the scene, yet the subconscious supplies it anyway.

Blank Rascal sets aside the exact purpose of dreams and asks what they are made of. To approach that question, he first compares dreams with reality.

The physical world and its smallest parts

Reality has the advantage of seeming measurable. Every physical object, the source says, consists of atoms. The word comes from the Greek atomos, meaning uncuttable or indivisible, although modern physics has split the atom into a nucleus and electrons. The video presents 118 known elements, 94 occurring in nature and 24 produced by human technology. That last number becomes another joke about the worth of ordinary work: people are now making atoms whilst the viewer goes about an apparently less useful day.

Hydrogen supplies the worked example. The simplest isotope, protium, contains one proton and one electron. Adding a neutron produces deuterium, adding another produces tritium, and adding a proton changes the atom into helium. The same basic account allows the speaker to say that physics can, in theory, turn one element into another, which makes the prospect of turning lead into gold resemble alchemy. He immediately turns the idea into a fake promotion for Blank Rascal NFTs and a currency called Blank Coin, complete with a promised rug pull.

Atoms also fail to exhaust the inventory of the universe. Light consists of photons, which can display wave-like or particle-like behaviour and seem to change their behaviour under observation. The source briefly names neutrinos, antimatter, dark matter and gravity as further reasons the universe exceeds ordinary intuition. Trillions of neutrinos pass through the body each second, according to the video, and the particles arise as a by-product of stellar nuclear fusion. Antimatter is described as a reversed counterpart to ordinary matter, with negatively charged protons and positively charged electrons, although the source’s account is deliberately rough. Dark matter receives the familiar estimate of 27 per cent of the universe despite remaining invisible. Gravity receives only the speaker’s frustration at how little he understands the force that keeps the world together.

This catalogue establishes the source’s physical baseline. The real world contains atoms, light and other entities that physics can describe with varying confidence. A dream seems to occupy a different category. It feels real whilst it occurs, yet it does not behave like an object that can be placed on a table.

The diamond that felt real

The video first asks whether dreams happen inside reality. The quick answer is that dreams are fantasies, followed by an immediate correction: they happen in the head, and the head remains in reality. Researchers can measure which brain areas become active during dreaming, yet the dream itself cannot be isolated in the way a physical object can. A thought cannot be bottled, and the feeling of a dream cannot be held in the hand.

The speaker then asks how large a dreamer is. A person is larger than an atom and smaller than a brain, at least by the scale that seems useful here. The dream contains a body and eyes, or at least a disembodied camera moving through incongruous scenes. That experience raises the question the video keeps postponing: does the dream occur within the universe, and does it have the same material basis as the things it depicts?

An orange diamond from one of the speaker’s dreams gives the question a physical texture. He steals it from his high school, discovers that it is opaque and carrot-coloured, and gets caught by his history teacher. The dream diamond is not carbon in the way an ordinary diamond is. It is a dream object, yet the speaker touches its smooth surface, feels its cold edges and sees its deep orange colour. The memory remains alongside waking memories, with the same sense that something happened.

The example presses on a problem in the word “illusion”. A cinema projection is an illusion made from photons, and a projector inside the head would give the dream a similar physical mechanism. The brain does produce dream images, although the eyes do not receive those images through the retinas. Rapid eye movement accompanies the dream, which leads to a short account of blindness. Someone who loses sight later in life can still dream visually. Someone born blind can dream through sound, taste, touch, smell and emotion, while visual content never formed part of their remembered sensory world.

The video compares a dream with a computer game. When a person remembers a game, the remembered object is the game world and the story lived through it, rather than the motionless body staring at the screen. The hardware consists of atoms, while the game appears through electrical signals and the movement of electrons. Dreams follow a related path through the brain, although the source says they run on ions rather than on the electrons and photons that carry a computer game to a screen.

Ions and the dream’s material basis

An ion is an atom with too many or too few electrons in its outer shell. The video uses sodium, potassium, calcium and chlorine as examples of charged atoms moving across the membranes of neurons. Those movements generate the electrical signals that support thought. The account is intentionally simple for a process that involves far more than a single set of particles, yet it gives the speaker a distinction he can carry through to the conclusion.

The imagined diamond is not a carbon object, and imagined water is not H₂O. A dream moon does not contain cheese simply because the dream presents it as a moon. The brain’s activity still depends on the movement of ions. The dream itself is an experience produced by physical activity, while the object inside the experience does not inherit the material composition it appears to have.

That distinction lets the source answer its title with two related claims. Dreams are not made of atoms in the same sense as a diamond or a moon. Atoms make dreams possible because an atomic brain creates the experience. Blank Rascal extends the thought into a comic image of more than eight billion people mentally travelling through other dimensions each night, then draws back from treating that image as physics. The mathematics of the brain may be known in outline, yet the experience still feels like a separate world.

Psychedelic experience supplies a comparison. Someone who takes a psychedelic drug may recognise similarities between hallucination and dreaming, including the sense of touching an impossible creature such as a warm magic dinosaur. The dinosaur never enters the physical world. The experience depends on molecules and neural activity, while the thing experienced remains mental.

Magic, simulation and the strange atom

The video’s central claim arrives through a deliberately blunt word. Dreams, daydreams, memories and thoughts are physical processes that produce experiences with no physical object corresponding to each image. They are caused by matter, yet the dream itself does not sit inside the physical world as another thing governed by the ordinary laws of physics. The speaker calls that phenomenon magic, then turns the word back toward the brain: a bundle of atoms can think, imagine and become frightened by its own activity.

This leads into the simulation question. Blank Rascal has long disliked asking whether the universe is a simulation because a simulation would simply be an imitation of another universe. If a computer keeps track of the roughly 100 quintillion atoms in the known universe and positions them all correctly, then that computer has become so powerful that the label “computer” explains very little. The source’s point is about description. Moving reality one level up does not remove the puzzle of what makes the higher level real.

The video then quotes Niels Bohr: “Everything we call real is made of things that cannot be regarded as real.” It applies the line to the atom, which older textbook images present as a small solar system even though atoms consist mostly of empty space. Electrons are better represented as clouds showing where they may be found, while the nucleus contains almost all the atom’s mass in a space roughly 100,000 times smaller than the whole atom. If an atom filled a football stadium, the nucleus would be about the size of a testicle.

Reality therefore becomes strange at both ends. The periodic table supplies the material from which stars, songs, tears, films, koalas and dreams emerge, yet its atoms are mostly empty space and its smallest constituents resist the solid picture that ordinary objects encourage. The waking world feels as miraculous as the dream world because a living, sentient pile of atoms can experience either one. The final question is why the universe would use such a pile of atoms to dream about a hippo eating salami whilst lava-skiing. The speaker has no answer, then says goodbye.

Limits

The description calls the video “very rudimentary physics and heavy speculation”, and that remains the right boundary for the claims above. The source gives no bibliography, chapter markers or links to studies. Its figures about nightmares, the number of elements, dark matter and the scale of the universe belong to the video’s narration unless independently sourced. Its account of dreaming, REM sleep, blindness, ions and psychedelic experience compresses complex research into comic explanation. The conclusion works as a philosophical distinction between a physical cause and a mental experience, while it leaves the status of consciousness open.

Further reading / references

The video attributes the quotation about reality to Niels Bohr. The attribution is disputed: the Niels Bohr quotation record places the sentence among misattributed quotations and identifies John Gribbin’s In Search of Schrödinger’s Cat: Quantum Physics and Reality (1984) as an earlier source. That qualification belongs to the reference, not to the video’s own argument, which uses the line as Bohr’s.
