Once I took 6.4g of some pretty good Hawaiian cubensis mushrooms, and I was having some pretty crazy visuals. I felt like I was swimming in geometric patterns for a while, which was beautiful, and everything was sparkly and light. After smoking a few bowls, I became utterly dissociated and couldn't tell the difference from what was real and what wasn't. I was sitting on a couch underneath this blue and green comforter, and I convinced myself that I was a mountain (the blanket sort of did look like one) and that I could see all the little trees and cliff areas. When I looked at the black rug below my feet, I began to hallucinate that I was in space. The flecks on the rug were actually stars, planets and galaxies, and I was floating inside it. After I managed to tear my gaze away from this beautiful image, I noticed that something odd was happening to my vision. There seemed to be a clear wall of distortion dividing the room in half vertically - it almost looked like a sheet of water, dragging the images behind it downwards. On the normal side of the room, all the items in the room had "trails" sweeping off of them towards the left, as if the image of the room was being dragged to the left. I convinced myself that I was watching space and time go by and distort. This went on for a while until I somehow managed to get up and stumble into my bed and underneath a white comforter. Although it was dark in the room, the white blanket transformed into clouds and the room became quite bright, and the walls and ceiling disappeared to reveal a clear blue sky. I scanned the horizon in amazement, and it felt like I was floating amongst the clouds. I closed my eyes for a minute, trying to take in what I had just seen. Behind my eyelids, detailed geometric patterns unfolded with explosions of color and light. I opened my eyes once again, but this time, I was in a rather dark environment. It seemed as if I was underwater, in a deep crevasse, and light was filtering down from the surface of this body of water. The entire room around me no longer existed. I was so lost in my hallucinations, I began to accept the underwater scene as real, and wondered if I had died, gone to heaven, and then returned as some sort of sea creature. I observed this peaceful scene for quite a while. At some time later on, I began to drift asleep, even though I was still hallucinating like crazy. I don't remember having any crazy dreams that night, and I woke up the next day feeling pretty refreshed. It was an amazing experience. Ive never seen anything like it in my life..
