Lucid dreaming and sleep paralysis are two agnostic descriptions of very real spiritual situations.
It appears that when fallen angels, are disobedient to their charge and are in a different domain, the laws of God are such that we are unable to take action in any fashion if they are present, until they violate our domain.
Sleep paralysis is a pseudo-intellectual attempt to disqualify a very real experience and memory of exposure to the angelic domain. It isn’t scientific, but rather it ignores direct human testimony to such events.
I’ve often wondered what I stumbled into when that happened, whether my brain was playing perceptual tricks or some sort of veil had been lifted.
In young adulthood I tried to understand it better and to resolve it by taking charge. Carlos Castaneda stuff.
Wrong. Don’t dabble.
