Didn't they already admit this in the post?
Occasionally I will use the word "microhydraulics" in these talks, even though it is not really proper technical jargon ... because no matter how old I get I can't shake the intuition that I was seeing my future in that childhood game.
Edit: I misread the post. Ignore my comment.
This is a kind of "X files" thread.
Post experiences which spooked you, which made you doubt reality, mathematical or physical laws, your sanity, memory or perception. The more improbable the better, but no second-hand legends please, share only what you personally experienced. If you had the event later explained rationally please use rot13 to avoid spoilers.
