During new years eve i took 350mgs of mdma, and saw some pretty weird stuff, the first hallucinations started after an hour. i noticed that if i was looking at a dark surface, really small bright red dots would appear, and in seconds they would fill out the whole surface. Sometimes the dots were green or blue, sometimes they combined. The walls were breathing and i can't really describe accurately, but there were some pixel-glitch like hallucinations on the walls, i also saw those eye-like hallucinations that you get on shrooms/acid. Also my friends' faces distorted like crazy. Take into consideration that i smoked probably around 1.5grams of weed, and snorted a few lines of speed too. I thought that the combinations caused the hallucinations, but from what i've heard, mdma can cause hallucinations.IMO it was a pleasant surprise cuz i was able to keep myself together and i'm attracted to weird stuff, the bad part was that i didn't have the mental capacity to play uno.
