When I was a kid I used to have this re-occuring dream where I was alone in my house and all the windows were blacked out...all the doors leading outside were open, but I was too afraid to leave because it was pitch black out there, like I would be stepping out into nothingness....I'd run around the house calling out, but I couldn't hear my voice...
by far the worst nightmare i've ever had and I had it quite a few times....
