scary trip

I guess to start i have to say i tried these pills many times before this happened... as did all of my friends, they were great pills so i dont know how this happened... yellow ferraris. i took one and a half (i naturally have a high tollerance to any medication or drug i take so i normally have to take 2 to feel anything, but i didnt care to roll hard that night) i feel great for the first 2 and a half 3 hours, rolling having a blast at my boyfriends b-day party, a few other of our friends rolled too. i re-roll at almost 3 hours like i normally do with another 1 and a half, and within 30 minutes my roll stops and i feel like im having a full blown acid trip, visuals and everything. i couldnt tell what was happening and what wasnt, i could see myself getting up from the couch to go to the bathroom or upstairs, but would open my eyes and be in the same spot on the couch so i dont know if i really moved or imagined it... this went on for about 5 hours before one of my friends sent me a text saying "dude, i feel like im on acid right now" made me feel better knowing it wasnt just me... but it didnt stop, i kept trying to calm myself down, and by the 8 hour mark, long after i should have stopped rolling i still felt it... once the sun came up i started to feel normal, but it was really weird, none of our friends felt it just me and this other girl... we all took the same pills from the same batch... dunno what happened it kinda scared me off rolling for a while...
