does somebody believe in the supernaturals?

Well to believe in God is easy , but the hard part is supernatural things...we can't really say ,but most of these beiefs evolved around superstition... sometimes people take things too literally, an intelligent person will take things both literally and figuratively ,so if someone says they saw a ghost, then people will write a book upon it and say they've heard someone has seen a ghost. It's mostly a shock to the person who have experienced it, so he/she exaggerated.

yes,even the bible speaks of bad spirits and other supernatural beings they are aliances of satan but as stated afraid in the power of God.
