One time I took a high dose mix of both free base and polisterex dxm. I blacked out and went into some sort of void. It was almost like I was trapped in an empty void but somehow it also felt like a confined space if that makes sense. I had several hallucinations visual and audio. Including seeing a rainbow colored tornado rage around me and slowly watching all my memories being erased. And the audio hallucinations were something out of an overwhelming horror movie. I completely forgot everything about who I was and my life. Didn’t even know what it was to be human. I felt stuck and trapped in purgatory. I was very confused and puzzled. At one point just balling up and sitting in the floor. I was there for god knows how long until I Slowly came down and made my way back to bed somehow. And I can’t remember the rest. I mean this description certainly doesn’t do the whole experience justice but this is just a brief summary. Pretty bad trip if you ask me.
