Simulation - Shadows and the Strangeness of Existence
Four short lessons on simulated worlds, Plato's cave, Philip K. Dick's 1974 experience and the strange fact that anything exists at all.
How sure are you that the world you see is the base level of reality? A film about nested simulations, Plato's prisoners, a science fiction writer's strange vision and the plain wonder of existing all ask how much of what feels real we have actually checked.
The 13th Floor and Nested Simulations
Published 2026-09-12 · Watch the short
The 1999 film The 13th Floor imagines scientists who build a digital recreation of a city. The people inside believe they are real, until one character notices inconsistencies and discovers that his world is itself a simulation built inside another reality.
That raises the idea of nesting. If a civilization can simulate worlds, those worlds might simulate worlds of their own, and so on. The short’s point is that once simulated worlds are possible, it is hard to prove that your level of reality is the original one.
Note
The simulation idea is presented as a philosophical question, not as evidence that we live in a simulation.
Plato’s Cave and the Shadows on the Wall
Published 2026-08-17 · Watch the short
Plato told the allegory through his teacher Socrates. Prisoners are chained in a cave facing a wall, and a fire behind them casts shadows of passing objects. Having seen nothing else, they take the shadows to be reality. One prisoner breaks free, sees the fire, then walks out into daylight and finds that everything he believed was a shadow of something much bigger.
| Element in the story | What it stands for |
|---|---|
| Shadows on the wall | Limited perception mistaken for the whole of reality |
| The freed prisoner | Someone who questions what they have been shown |
| Others who disbelieve him | Resistance to challenging ideas |
The short applies this to algorithmic feeds, which show you more of what you already clicked on and quietly filter out disagreement. That modern comparison is the video’s argument rather than a finding.
Philip K. Dick and the Pink Beam of 1974
Published 2026-09-29 · Watch the short
Philip K. Dick wrote stories about simulated realities and false memories that became Blade Runner, Total Recall and Minority Report. In February 1974, the video says, a woman delivering medication wore a golden fish necklace, and Dick described a beam of pink light that brought a flood of structured information and a sense of an intelligence he called VALIS.
For the next eight years he wrote about it in a private work known as the Exegesis, about 8,000 pages. He considered many explanations, including a past life in ancient Rome, divine contact and an alien satellite, and never settled on one. The short’s point is that a man who spent his career imagining false realities could not tell whether this was the most real event of his life or a collapse of his sense of reality.
Important
This is the video’s account of Dick’s own description. It is not established fact, and it is not medical or psychological advice or a diagnosis.
Why Is There Anything at All?
Published 2026-06-26 · Watch the short
The last short says we have normalized existence. We wake up in a body with thoughts, memories and emotions, and treat it as ordinary, even though, as the video puts it, nobody truly knows what consciousness is or why anything exists. We work, scroll and worry about small problems while standing inside a great mystery, and the short suggests existence should still fill us with wonder.
Conclusion
Simulated cities, cave shadows, a visionary writer and the bare fact of existence share one lesson. Our sense of reality is something we have rarely examined, and asking how we know what we know is the first step toward seeing more of it.
FAQ
- His world is the base level of reality
- His world is a simulation built inside another reality
- He is dreaming
- The city never existed
(2) He notices inconsistencies and learns his world is not the base level of reality.
In Plato’s cave, the prisoners know the shadows are only representations of real objects.
False. Having seen nothing else, they believe the shadows are reality itself.
- Through the weather
- Through algorithmic feeds that show more of what you already clicked
- Through ancient architecture
- Through cave tourism
(2) The short argues that feeds filter out disagreement and keep you comfortable inside a version of reality, which is the video’s own comparison.
- A beam of pink light that brought a flood of information
- A sudden storm
- A lost manuscript
- A message from a film studio
(1) This is Dick’s own description as relayed in the video. It is the video’s account and not established fact.
The short says Dick settled on a single explanation for his 1974 experience.
False. In the Exegesis he cycled through many explanations and never settled on one.
