Bear with me, for some quickly-concocted words on an internet forum don't hold a candle to thriller writing, so it'll *seem* lame, but here goes... Somewhere between 4 and 6 of us - something relates us to one another but it wasn't clear - have nightly missions in these buildings or houses. We have to do something overnight but not trigger this "event" in order to be successful. The "event" keeps occurring; somehow we keep triggering it and "it" happens while we're asleep. The "event" would seem to have been, to a sleeping individual (as the rest of the group, besides me, sleeps through them), to be a temporal reset where our timeline was severed and we were returned to the last branching point we started from. The next night we'd start down a different timeline with different building but same mission, and so on. ... but I knew what actually happened during an "event", because I secretly was awake throughout them, but had to stay absolutely still to avoid a worse fate. A figure in a huge white cloak, perhaps 7 ft tall, no face but black from neck up, with a triple-horned black "crown" would appear with an earsplitting metallic BANG about 200 ft from the building and begin moving slowly toward it. About 10 seconds later a smaller, about 5 ft high completely white cloaked minion would appear about 100 ft from the building and move more rapidly toward the building. I look out the window and see these things each night, hearing the movie-theater volume BANG BANG BANG get impossibly louder as the beings moved closer. I recall this sequence happening perhaps 6 repetitions in different places before the temporal reset - I didn't see the beings enter the building or what they did to us. Then, they noticed me awake upon entering. The smaller all-white creature swiftly crossed the room, circled the couch on which I was sleeping several times, then adrenaline woke me up. I was burning hot, heart racing, adrenaline pumping. I was about to fall asleep again but forced myself awake to avoid re-entering that nightmare. What. The. Fuck. you traitorous subconscious!
