This wasnt really a nightmare, just kinda coincidence, or something... I jump into a lake, and I am swimming around, and I dive under to reach the bottom, upon my ascent, I am running out of breath. Suddenly, the top of the lake turns hard, and I canot break through. I am bashing my head against the top to break free. I am runing out of air, and I can barely breath. I am drowning, and I cant get any air.
I snap back awake, with my head between the matress and the headboard, with my face buried in the pillow, smothering me.
