I have had both audio and visual hallucintations while tripping....I actually enjoyed the audio, alot of echos.....Open eyed visuals were really fun!, the flowers, geometric shapes forming in a puddle of water...And then the patterns, sweet jesus them patterns were beautiful. I actually fell into a silohoutte of myself and then said "woah" got up and started the trippage, so i know what your talking about.....iam not sure if silohoutte is spelt right but i do know its close
