I’ve had some interesting hallucinations in my day.
Once, on salvia, nitrous oxide and pot, I was lying around in my friend’s room with all the lights off and the computer playing the album “Hail to the Thief” by Radiohead, with a Winamp visualizer going full-screen. I started flying through the “tunnels” presented by the visualizer, and then I began to fully experience the lives of hundreds of thousands of people, all in about 20 minutes. I saw, did, felt, and heard everything they saw, did, felt and heard, from birth to death, each and every single one of them, and after each one died I could use the knowledge I gained in their life in the next life (kind of a reincarnation sort of thing). It was quite terrifying for the first couple of minutes, but once I got into the hang of it I rather liked it.
Another time, on 300 mg of DXM, I saw a bunch of storefronts…a bunch of random stores people owned. I was having really deep psychedelic thoughts about how life is so fake, and all those store owners set up their store every day and do all their fake stuff all day long and go home and commit more fakery before going to bed and then waking up the next morning to do it all over again. I also saw a powerful vision of what would happen to me 5 years down the line if I didn’t keep my drug use in control. I saw myself failing at life, but as a possibility; that is, I saw that it was very possible for me to get addicted to something and fail at life, but it was also very possible to keep my drug use in check as I was doing and still do. Basically a ‘you have the power to keep this from happening; don’t fuck up’ thing. My friend and I then watched an online Shockwave animated series called Catman; I found out a week later that Catman had dialogue. The sound was up plenty loud enough to hear it at the time, I just apparently blocked out all the dialogue. I just thought at the time that the idea was it was a bunch of cool looking animations with interesting background music.
Once, on just weed, I had closed-eye visuals of a hallway, maybe 10 feet long, which I was standing at one end of and looking down to the other end of. The hallway started stretching and getting longer and longer, until it was miles and miles long and I could see the whole way. I opened my eyes, closed them again, and saw the same sort of thing but with a palm-tree-lined road rather than a hallway.
Oh, and sometimes on DXM (which is, BTW, legal; may be illegal in high doses, I’m not sure), when I close my eyes I can still see all around me. It’s like a negative of a picture, though; it’s all dark where it would (if my eyes were open) be light. Very weird. I’ve heard of two other friends experiencing the same thing. And this isn’t just a thing where my eyes are closed and I think I see the outside world; I really do see it. And one time when one of my friends was doing that, I waved my hand in front of her face when her eyes were closed and she didn’t know I was going to wave my hand in front of her, and she saw it. I have no idea what that’s about. I swear to God it’s all true, though.
