Oh I thought of this other experience last night, and I think its worth posting. About two years ago, I took an extremely high dose of DXM (I believe it was 1.8g and I'm about 160 lbs.) I had tons of experience with DXM, and had taken doses approaching this before. This experience was completely different. I was lying on my bed, just letting the drug do its thing, and all of a sudden I got the strangest pain in my legs. It didn't feel like any pain I'd ever felt before, not because it was weaker or stronger, it was just an entirely new sort of pain. I looked down, and while everything in my vision looked normal, my legs did *not*. They were stretching and bending at an impossible angle (like looking at something underwater at an angle) and as they stretched out and to my right, my feet looked like they were fading into nothingness, even though I could see objects *beyond* my feet just fine. I had the distinct sensation of being jerked out of my body, it felt something like the drop on a roller coaster, and suddenly I was in two places at once. I could still see my body and my whole room, but I could *sense* that I was in another place at the same time. I heard crunching glass and metal, a lot like the sound of being in a car accident. I could also hear klaxon alarms going off, a strange hooting sound in the background. All of a sudden, I had a clear-as-day realization and knew where I was - I was in a spacecraft, caught in a declining orbit around a black hole, approaching the event horizon. Time was dilating because of the effects of the singularity, and my crew and myself were unable to escape the gravity well. We had made the decision to use our life support pods (which included simulations we inserted our consciousnesses in, in order to avoid brain death during the suspended animation process). We knew that because of the effects and nature of a black hole, it would literally be forever before we reached the singularity and we'd just be orbiting forever (or at least that is how we would experience it.) Our simulations to keep our brains alive were designed to contain both pleasure and pain, because our human brains are designed to reject any experience it views as unrealistic and are really good at detecting when they're being fooled. I don't know if the sims were fully written programs, or some sort of lifelike video game where you make your own choices. But as I was experiencing getting closer to the event horizon of the black hole in my "real" life, and the ship suffered damage, my brain (which was still engaged in the sim - *this* life) tried to rationalize it inside of the sim as a drug experience. Which, if that's the case, none of you are real and I'm talking to myself, but yeah...
Hope that was at least interesting to read if nothing else lol...still hoping to hear about other peoples' experiences, if they have any! Thanks for reading =)
