I have had no such experiences and, if I did, I would assume it was a hallucination.

I believe the mind is incredibly complex and powerful. I believe it is constantly adjusting ones perception in order to align it with ones reality. Insanity is the imbalance of this equation. Much of this percieved demonic actively is the result of the mind adjusting perception to make sense of reality. Just my humble opinion.

If you ever met my mother in-law you WOULD believe demons exist - TRUST me! in fact Satan him self checks under his bed before he goes to sleep ...... just in case she's there waiting in the darkness.

I had a couple of experiences when I truly felt not only a sense of evil, even malevolence, but that that sense was coming from a presence in the room with me. The second time was incredibly intense, as I felt the fear instilled by that presence just about to overwhelm me. There was no apparition by the way. Just a strong sense of not being the only person in the room. Like I was being watched. The first time was not as bad which happened at another locale. Only that time I found myself looking directly at a particular place in the room as if someone was there, though I didn't see anything.

I consider myself atheist, but have had very strange encounters that lead me to believe that there are "supernatural" things. It might all be in my head, explainable by science, a delusion I experienced, who knows. They were things I personally experienced and I have to believe in my own perspective.

I've seen evil. I've done evil. True evil. The kind of things you hear about in a British accent emploring the audience to take note of and demonize. I associated with the kind of evil reserved for movie scripts and prime time drama storylines. I committed myself fully to the exploration and embrace of evil actions, evil thoughts and evil plans.

None if it is worth it.

Not only recognizing but embracing evil leaves scars on you that don't heal. Ever. But embracing something higher does make life seem like it is possible. Denying yourself the sadism of evil and aspiring to do the most real, long lasting good helps ease the conscience of playing with things, and thoughts, better left alone.

The Bible has a lot of credible historical objects and facts to back it up. There is a museum in DC now, the museum of the Bible.

Earlier in life I was somewhat conflicted in my beliefs but latter I realized it was kind of hard to believe in anything that there was no evidence even existed.

No. Though young, i hold my confidence in the inaccuracy of human senses/perception tools. In other words, i think all of these "encounters" can be explained by science, such as a misinterpretation of the information the individual has taken in (mistaking a shadow or a noise as something other than what it is).

Never had an encounter with anything that could fall under the supernatural category (demonic possession, magic, witches, ghosts and hauntings etc.). As a youth I believed in all of the above and more, but as time went on and I realized that I had no evidence to back up my beliefs, I started questioning things. Concrete evidence could certainly change my mind, until then I remain skeptical.

One more quick thought... could it be that these beings humanity refers to as angels and demons is in reality nothing more than extraterrestrial creatures, and for lack of a better description some people just refer to them as angels and demons?
