Well, to start off, having taken both Cid, and Shrooms, I do tend to find differences in the speciic visuals I get. First off with Cid, I tend to see more movement in patterns, melting/breathing, shifting in patterns. The biggest thing that I have gotten while tripping was synthasia, the physical feeling of music. I do think that there was a very mild dose of PCP in the cid though. But my acid experiences have tended to be more color intensity, and breathing/moving of objects, also to include plastic reality, and reality wall paper(ie. reality ends at a certin distance from you, and you see the world, but it just looks like it was printed on wall paper, but the wall paper keeps moving with you, so you never get to the wall). And the occasional discussion with inanimate objects. The strangest thing with Cid is the time dialation, I was at the DEMF and it would seem like 10 minutes would go by between when my friends took turns speaking to each other. Basicaly I have only gotten level 3 hallucinations off of cid. With shrooms, I have noticed that I tend to have higher level hallucinations, like the celing will dissapear, and there was my good friend who was laying next to me, and I saw multiple copies of her dancing where the celing was, then she morphed in to another girl who I did not know. Also I have noticed that with shrooms it is easier to distort gravity by laying on your back, and putting your legs against a wall or bed, like you were sitting on the wall, and after a short time you actually for get that you are laying down and it seems as though you are sitting with the celing as a wall infront of you. My shroom experiences have included things breathing/melting and movement of inanimate objects, but I have had more higher level hallucinations, including what i believe to be level 5 halucinations, where reality actualy pretty well dissapeared, and things just didn't mean any thing to me. Also I have found that I tend to do more thinking with shrooms then cid. But I strongly agree that you should look in to what you will be takeing more before you take it. Just be sure to know exactly what you are putting in your body, and what the repercussions can be, as well as any potential dangers.
