How do you know when ghosts are inside of you?

There is no such thing as being possesed, but, i do believe in supernatural beings and dark energy wich some special/sensitive feel or sense when they've been mad or unhappy. all u have 2 do 2 get rid of anything is say the Our Father. Mean it. Really, truly, mean it. they can't hurt u but they can scare the crap out of u.
