Darling perfect1, you my dear, have my greatest empathy as I too suffer with nightmares related directly to my whole life being in the borg. Others here also have them. Some also have sleep paralysis, which can seem to a semi-conscious mind to be a demon attack. I don't know if you or I or anyone else here with this problem will overcome them but...knowing why they are happening, and with sleep paralysis, what is happening does give you a small weapon to try to talk to your mind about what just occured.
T he more I read about 'our' collective harrowing experience with the WTBTS, the more I begin to think some (myself, for sure) have classic symptoms of post-traumatic stress syndrome, especially if being a born-in or an almost born-in. Mental help may be in order.
perfect1-you a definitely not alone.
