shroomcreep 

That feeling of mild discomfort to slight nauseous paranoia you get, when tripping on shrooms with friends, that somebody's looking over your shoulder, but it's just you trippin' balls.

Willem: "Hey, man, where were you? You don't look too good."
Niel: "Yeah, man, I'm good bro. Just had to take a break from all you snakes cos I was feelin' a bit creepy. Had a massive contemplation session on my bed and almost faded."
Seb: "Yep, sounds like you got the shroomcreep, son. Here, dab some MaDMAn. Should set you right."
