well i was on ecstasy..never thought i would actually hallucinate while rollin but hey i did....it wasnt "during" the peaks or nothin..it was the day after rollin..im guessing it wasnt PURE MDMA..or maybe it was but...i was layin on my bed tired as shit bcuz of rollin...so im just layin there..and i turn my head right and look at the corner of the ceiling..then i see transparent spiders..about the size of my head..i saw about 5 of em standing next to one another..and they were moving their legs..and twitchin once in awhile..then i guess they saw me staring at em..so they started crawling hella fast my way..and i kinda got freaked..but when they reached me..i just felt like a slight light headedness...and when they reach me..they just go through me n shit..and there was only five but then they keep appearing in the same spot the others were..and then my room was filled with "colorful" smoke..and it was like myst floating down to the floor..but when i blew on it..it would be like slow motion smoke moving out of the way from my blow of air..haha.anyways..interesting..ima smoke some laced weed(laced w/ ecstasy) to see wat its like..peace
