without getting too metaphysical here...
I believe in the concept that there are higher spirit realms above humanity and lower realms(not sure about them being spirit per se) WITHIN humanity. I am not explaining this very well, I know because already I have confused myself...
ok, the Norse idea of 9 worlds, or the other pagan ideas of a tree of life sorta thing---I do believe there are spirits outside of the human creature, but I also believe there are 'levels' with in us as we are just a reflection of all of the Universe. So I do believe there can be 'demons'--BUT I do not believe they are naturally malevolent spirits outside of humanity intent on doing us harm. I also believe 99% of the so-called demons that JWs and other religions believe in, do not come from outside of humanity. I think it is the dualism inside of us and the deeper levels of ourselves. And I absolutely do not underestimate the power of our inner demons. Humans are very powerful creatures and we have no concept of it for the most part.
So....WHATEVER you BELIEVE chases away these demons, will chase them away since they are your own 'demons'. If it is a true spirit creature, I have never had the need to chase them away---if they scare me I ask them to go and they do. I have asked them what they wanted and when I found out why they were communicating with me---my fear has dissipated.
If you want to believe that saying a name or 'magick word' chases away the bad boogers of life--or a rabbit's foot or a prayer--then it will work until you doubt it.
I do not believe it is inferior or childish or superstitious to believe this way, so I am not putting anyone down. I think the human animal is always evolving and at this point in our development symbol and ritual are still necessary.
As a JW kid I had many many scary 'demon' experiences. As an XJW adult I have many many 'supernatural' experiences. However, the demon experiences I had as a kid were resolved in a dream about a year after I left the JWs.
I had 'the demon dream'--that recurring nightmare that I have had ever since I was 5 or 6 years old where the doors slam and the lights go out and the demons scream and you can't get your voice to say 'Jehovah' and you wake up in a total panic and pray the rest of the night out loud.... one difference this time. This time I did not try to say 'Jehovah' or to wake myself up. This time I ran into the evil black cloud that was screaming at me and I embarced it. I said 'nuh-uh'(as in the negative to uh-huh) and I grabbed that demon and I hugged the $h!t out of it! Guess what? it got all warm and it turned into a giant brown cloud of chocolate! I actually woke up tasting chocolate! What a trip! I have never had that dream again! In fact I have not been scared by any demons since. I have had visits by other spirits, but they were not scary. The worst demons were inside me, and I literally embraced them and they turned into chocolate. Dang even I could figure that one out without a visit to a Jungian psychoanalyst!
So while there will be many who think that a belief in any spirits or communication with them is just hogwash, I am not one of them. I respect spirits and 'demons'. But I do not fear them. The only ones who can control me are the ones that are 'in' me, and now I know I can change that.
I guess that makes us all possessed to some degree huh?
