I used to be terrified of demons and if I felt I had sinned in some way that would mean jehovah taking his blessing away I would sleep with the lights on.
I used to to wake myself up in my sleep and be conscious but still paralysed and hear a buzzing sound. I thought it was demon and would try and say "Jehovah" but only an earthly demonic voice would emanate from me. I thought I was possessed. As I was fading I did some research on this and found I was experiencing lucid dreams which is apparently quite common. It's a phenomenon that occurs usually as you're waking up.
in fact lucid dreams also explains away the stories my mum and my sister told me of their own "demonic experiences". It obviously runs in the family.
Nowadays I'm a cynic but I do acknowledge there are some unexplained phenomena for which maybe science hasn't discovered the cause. I think maybe humans have more powers than we realise - such as the seemingly telepathic connection between twins. But I don't believe this is from a spirit realm
