I hallucinate, but only when i smoke a lot of weed during my roll. I've hallucinated twice while rolling; he first time was great, the second time was ridiculous.
The first time I was at a roll party and we had a sick $400 laser light that moved to the beat of the music and a fog machine. The smoke moving through these lasers was unbelievably majestic, its like the smoke and lights were telling a story. Every now and then the fog machine would let out small puffs of smoke and it would seem like the smoke was super complex and intricate all while maintaining its beauty. When the laser light was pointing its laser onto the floor, i saw a sea of green covering the ground and all the lasers hitting the floor were small horses running back and forth to the beat of the music.
The second time was at the Electric Daisy Carnival. I was two pills deep right as deadmau5 came on, my friends and I shared a huge joint between the three of us. Not long after that, I was floored, lost my sense of reality and all that. Deadmau5's visuals were indescribable, he had squares going into and out of other squares and shit, i was completely mindfucked. I would look at the crowd in front of me and i would see them as slow moving waves, kinda like people jumping up and down in slow motion. After a while, his music got too intense for me so we went and sat in the stands. I looked at the crowd on the other side of the coliseum and they were morphed into large multi-colored blobs moving through each other just like germs and cells would on a microscopic level.
Both times I really enjoyed my hallucinations. Its definitely what makes ecstasy that much more magical
