Years ago I used to get attacked quite a lot, I guess I had something they needed, that was until I realised that I was just as powerfull as they and in some cases way more. One night years ago I was relaxing in bed ready for sleep when a pressence came into my room and tried to break into the outer layer of my energy field. I gave an energetic shove with my field to push it away and was promptly pushed across the bed and into the wall for real. Nowadays If they mess with me I lucid dream and harrass their asses, I cornered one particularly nasty one not long ago and told it to back off. I am almost certain that this kind of sucker is responsible for a lot of the nightmares that people have, they have an unusual ability to induce absolute fear into their victims which is almost electrical in its nature. Anyway thats the goal, when we experience fear we give off the wavelengths they need to sustain themselves and move to the next victim
Post edit. Just to clarify lucid dreaming is not astral projection, but when these entities visit a sleeping person they manipulate their dreams into seeing all kinds of horrors.
