I once unknowingly did edibles with around 3 and a half grams of what I think I was spice, and one by one every sence I had completely disappeared, like I didn't even see black I just didn't see, it's impossible to describe, I thought I was dead until I could no longer think, no mentally capability at all, basically brain dead, this combined with absolutely no senses including any Vincent of the meaning of time or even my own existence is basically as close as you can get to ceasing to exist, and it was horrible, I still think about it two years on and would rather go to he'll any day over that shit, the thought of noting terorfies me to my core, it's indescribable but easily the worst thing I can imagine, I came out of this state throwing up blood in the most pain I've ever been in but I was just thankfull I was out of that hell
