I asked if psychics are real no one said yes 3 said demonic?

I was very surprised that no one believed that psychic powers might be real.Three of my responses said that these spirits were demonic.So I ask..How can we say there are demons lurking about and not believe there is a psychic connection.The theory I'm looking for is proof of life after death.I thought if these psychics could talk to people on the other side then there's life after death.My answers did not support this SO...Demons may also prove this to me.Where are the demons and wheres the proof??
