Actual Orisha exorcism shit is pretty terrifying... I knew a woman who was a medical anthropologist who had to find witch doctors in the Caribbean community of Miami to cure people who had been cursed with this sort of thing.

Spiritual mania is very weird and it can happen to anyone, even atheists.

I always thought things like this could be attributed to hypnotic suggestion.
But I suppose if its a sort of mania, the patient could believe in any sort of fantasy with a frightening intensity, as seen here.
Or it could be a stunt.
Or it could be legit.
Who's to say?

He seems to be break dancing to slow-core. Perhaps the demon is codeine?

Also: I have never seen an actual geek act, until just now. Thanks POETV!
