When our physical body dies, our Soul/Spirit/Consciousness survives and goes to the Spiritual Realms where God decides what happens next.
Apparently there is some situations where "Tramp Souls" remain earthbound due to strong material urges and attachments.
They look for foolishly passive mentalities so that they can inhabit their bodies.
Jesus and the Apostles cast out these "demons" in different stories in the Bible.
Lately I have been watching a TV show called Paranormal Activity Caught on Camera.
The program shows "home videos" of things from UFO's to ghostly encounters.
There are plenty of videos showing what appears to be a "spirit" with a physical form walking down the street, in a house and so forth.
Also with some of their sophisticated equipment, they were able to record audio from the spirits.
Sometimes voices could be heard with no audio equipment.
There is something going on here, obviously.
What do you think is going on with these "ghosts"?
It seems that not all of them want to possess a body but just seem to be content with haunting a house or....whatever.
