As a JW were taught all about demons but I never had an incident. My wife believes wholeheartedly says her family including her has had problems with them. I have met people that even non religious people that say they have experienced a ghost or a spirit. Funny thing about my wife is she has gone crazy when an object is in the house she thinks is demonized like a book or something. She will put it out side or get rid of it. The thing is she hasn't had a problem with demons in over a year and I have in the house the worst book of all Crisis of Conscience, LOL
Anyway what's your thoughts on these creatures, do they exist, are they just in peoples minds and if so why do non religious people still seem to think their real???
