(CNN) – The man is strapped onto a gurney and restrained, yet he is singing, making faces and twitching.

“You know where you’re at?” a paramedic asks him, but Freddy Sharp can’t answer. He was, he explained later, off in his own world after overdosing on synthetic drugs known as “bath salts.”

“I’d never experienced anything like that,” Sharp told CNN’s Don Lemon. “It really actually scared me pretty bad.”

He said he was hallucinating about being in a mental hospital and being possessed by Jason Voorhees, the character from the “Friday the 13th” movies.

“I just felt all kinds of crazy,” said Sharp, now 27, of Tennessee, who says he hasn’t used bath salts in months.

“It felt so evil. It felt like the darkest, evilest thing imaginable.”
