It's kinda funny actually, but everytime when I am on acid, I see kaleidoscopes everywhere and I just don't understand why I don't see them when I'm sober. It's really a stupid thought actually but it keeps me busy. I feel quite sober on acid (not that I've done it so much), but at some periods of the trip, you almost forget that you've taken lsd and see those kaleidoscopes everywhere. I even once took a picture of some trees, convincing myself I would see those kaleidoscopes later on, on the photo. Just stupid thinking but I don't have that thought with other hallucinogen drugs, most of the time I can seperate the hallucinations from reality, and in my subconscious , something is saying me that this is not real like on shrooms, but on acid it's really a different story for me. Other people having the same (well if you can say: ) 'problems'.
