Do you believe in the supernatural? If so, why?

i’ve never seen anything paranormal or strange myself, but i’ve heard things from people i know have no reason to lie. They aren’t writing any books, and in just about every case only told me, or one or two other people. I’d put it down to hallucinations, except i know they don’t hallucinate or use drugs. I keep an open mind due to this, the universe is a strange place and we don’t know everything about it.
