Okay want to say, last year I had a hallucination. Hallucination was I saw a red digital timer in my eye counting down time. The hallucination was unlike most hallucinations. This is because it wasn't really a delusion, I did not believe in monsters or ghosts or anything like that. Instead it was more like a videogames, where something was stuck to my eye, like a gui, hud. Like I was a cyborg robot in a videogame, with text on my eye. I googled about hallucinations, it says this This is why I am not sure what I did was a hallucination. Because hallucinations are silly and make you believe in things that look real. But none of this looked real, it looked fake, like a robot in a game. I was not delusional, I did not for a minute believe the hallucination was part of physical space, instead it felt like I had a robot eye, with a GUI on it of text. The other thing to note is, the hallucination faded to an intense red slowly, like an opacity fadeout of a videogame. And the hallucination was not part of physical space, it was like a 2d overlay on my eye that moved with my eye, and did not move with 3d space. So the other thing is, neurologist says I have weird things in my brain, after he scanned me. He has no idea what they are, but he does not think it is cancer. So the weird stuff in my brain is unexplained. The other thing is, 2 years ago I was taking a nap and closing my eyes. When I close my eyes I usually just see blobs of color. But this time, I closed my eyes and saw computer screens that looked like 1995 unlike any computer screen I had seen. Everything was in a new language too. The language looked slightly russian but it was not Russian. My immediate hypothesis was that I was on the computer too long, so I opened my laptop and I realized the GUI of the laptop did not look the same as the GUI I saw imprinted in my brain. The spacing was different, the colors were different, the colors were in such a way that as not to be simply inverted, and the text was different. So my hypothesis is that we could be living in a simulation. Neil de grasse tyson says sim theory is plausible.
