Do paranormal entities exist? (This includes Ghosts Poltergeist Demons, Spirits ECT

In the study of theology and philosophy the creation of orders of angelic beings occured along with the universe. Angels, unlike humans, were created with a deep knowlege of good and evil. LIKE humans they were also endowed with free will. Those spiritual beings, (angels) who used their free will to separate from the presence of God, are referred to as demons, (among many other things). They manifest themselves in myriad ways in their interaction with the human race, and while they do not possess bodies, as we do, they are able to manipulate elements of nature to make their presence known by varying degrees, to humans.

While I do sincerely believe the existence of demons, there is no good evidence that we humans should be encouraging their presence to our senses in any way. In fact there is much evidence to the contrary. Demonic angels are most likely make up a great number, if not all of what we attribute to phenomena such as "ghosts" and "poltergeists" etc. It is part of their deception abilities that they can even present themselves in positive images which are enticing to us, such as the souls of our relatives or ancestors who have not yet and what not. They come especially to people who invite them by dabbling in both ancient and "new age" spiritualism, such as mediums, tarot, palm reading, phrenology, halucinogenic drugs, numerology, automatic hand writing, channeling, pop astrology, Ouija boards, hypnotism, seances, etc. etc. The list of our dabblings is endless and exhaustive.

While my mind isn't completely closed off to the idea, I'm becoming less and less convinced of other types of things all the time. Stuff like extra-terrestial beings and bigfoot and stuff like that, but those generally aren't discussed as "supernatural", so not sure if they're part of this question.
