I always have trouble sleeping, it can take hours for me to drift off to sleep. I never remember my dreams. I usually try to go to sleep between 6am and 7am. I was reading a book (The Lost Symbol) and listening to classical music (Bach) around 1am today. I suddenly felt extremely tired, and closed my eyes for a moment. Immediately, I felt cold, then I saw a woman in the darkness wearing a white dress, and she opened her mouth and started making a sound that sounded a lot like an alarm clock. Her teeth looked like long white nails, sort of like some deep oceanic fish, like the Anoplogaster Cornuta. I immediately work up, and found that only a moment had passed. I then felt the same draining feeling and the next thing I know I was dreaming. I was in a burning building, but I felt cold, and I was with some sort of group of people trying to get to the center of the fire, but not exactly firefighter. Then random people like things that were too blurry to see keep running up and trying to get me to breath from different air tanks. The first one made me feel tired and light headed, the second made me confused, and the third one made me feel as if I were burning. Dazed, confused, and barely awake, I stumbled through a fenced gate near some lockers, and found that same woman from before, only this time she was standing in a thick puddle of blood, she opened her mouth and made that same high pitched oscillating buzzing sound as before, and I woke up feeling the same as I did in the dream. Then I woke up and got a cup of tea, opened iTunes, and watched an episode of Family Guy to clear my mind.
The first part seemed extremely real, and I was only out for about a minuet at most. I could still hear it for a few seconds after I opened my eyes and was awake. That was odd.
