Who's done LSD?

[Plot]

I basically describe it as the difference between a hallucination and a delusion.
A hallucination is seeing something that is physically in front of you changing/warping.
A delusion is Darth Vader walking into the room and sabering your friends head.
...you experience trails (moving objects leaving a kinda visual echo and shimmering,
I dropt shrooms and went to the pub, drank like 8 pints of guiness and I was watching the
carpet which had turned into worms, (not really just all the fibres were wiggling)
After dropping 2 trips on another occasion the wall in the dining room seemed to become
a vortex and everything on it was spiralling into itself the (calender, clock, poster etc..)
But you also trip out, I remember once being in a room and hearing my flatmates in the room next door and thinking stragers had home invaded the house, climbed out the window and hid in
the garden for about a minute before having a lol moment to myself and having to go back and knock on the front door, my mates were like 'what the fuck, how'd you end up outside roflz.'
