Shitloads of people have written trip reports while being on acid or any other psychedelic, just go search the forums, justinsane did one a few weeks ago on his acid trip, which detailed much more than 'Oh shiiiiiit man I'm fucked', I did one on DMT, and once you see the length of the trip reports, u'll see why the majority just choose 'Oh shiiiiiiiit man I'm fucked', as those who have tripped hard know where ure coming from, and those that don't there's no point in trying to explain, as you sound like a crazy bastard.
