On laced weed (PCP we suspect) I was sitting in my friend's room, she had a hamster in a cage with a wheel, when it ran in the wheel the sound echoed thru the room (which was basically dead silent) and I felt like the floor was shaking because I was feeling the sound of the hamster. I literally couldn't stand because my mind was so set on the fact that the floor was shaking (which it wasn't).

Hearing colours to me is like, I dunno... when you listen to a song and you almost see a colour in the back of your head, feeling a colour is like when you think about what a colour would represent, (ex: red; anger, lust, ect) and then you feel that.

I think it depends on the drug + hallucinations.
