The only thing i can think of, and ive seen this happen in the past with mates. Cocaine and amphetimines make you stay away, if your taking alot, you can be up for days! And this causes hallucinations really bad. Ive seen friends go home and unscrew everything electrical in there house, thinking C.I.D or watching them. Pulling wires off the wall. One lad i know was naked in a back yard of someone, because he thought the police have bugged his clothes.
So i think, but i could be wrong he just needs a lot of rest and come off the coke and everything else.
My mate who was addicted to wiz. Is now in a mental home, it was sad seeing him deteriate. But all this was started from no sleep and the drugs.
