I definitely reached the K- hole level last night. Lost complete awareness of my body and went through several levels of existence before ending up on what i will call the hardware level since it seemed that it was all a strange computer. There are two levels I remember better than the others. The first was a world that was fairly close to this one, but inhabited by many strange creatures. There were trees and plants like in this world, though they didn't look quite the same. I felt like I had some kind of power, though I am not sure what it was. A large, colorful bird flew overhead while I was walking or drifting down a path and it left rainbows and colorful dust falling behind it. As far as I was concerned, everything I experienced in the K-hole was my real life and I had little or no memory of anything before. I stayed here in this world for what seemed quite a while. I was happy there. I was pulled out of that world. I don't remember how it happened or what it felt like. I no longer had even an imagined body that was anything like a real one, if I had one at all. I went through one or more poorly defined levels of existence that just blurred together before arriving at a level I find hard to describe. I would stay here for what seemed an enormous amount of time. It wasn't too bad at first, but quickly became hellish. I was like a bunch of rubberbands tangled and looped together, moving along with other masses of tangled rubberbands. For some reason it began to feel like torture. I eventually got down to the point where I was the only one of things things I could really detect, though I knew there were others. I was asking for help. I wanted out of there. I asked what I guess might be God for help, but at the time I thought maybe I was one of many gods who had created false universes to escape in to. I didn't know if I would be in that state forever or not. I could remember something of a past before it got like this, and believed it to have been a false reality. I could remember the first K-hole level better than my real life at this point, though some of both lives were available. I would have been happy to go back to either one. I did eventually return to this life, but only after another enormous amount of time seemed to pass. I was very confused and still felt like I was in another world when I did come out of the K-hole. I was in a dark room, with the only lights being from the digital clock and optical mouse. I could not understand what they were. I eventually began to understand things a little better and came to understand what had happened. Now I am out of ketamine. That is okay, I don't need any more right now.
Maybe I'll try this again in a month or two, if I can get some more. Maybe I'll stay on/in (a) good level(s) next time. Right now there is still at least a little fear that I could not only end back up in the bad place, but be stuck there for a long time, possibly forever.
The description I gave for the second reality I described can't come close to what it was really like. I have no way to describe it in a way that could capture what it was really like on a mental or sensory level.
I know I feel great today! So happy to be alive and in the same old world I usually want to escape from. It feels like I have been touched by something beautiful on some deep level I can't describe. It also seems more likely at the moment that I will survive death. All of this will likely fade quickly with time, but it can be good for now.
