I've had my share of awesome dreams, but I'll say one of the best was a horror dream.
Yes, a horror dream.
Now, the dream started as an old movie and from third-person view. You know, that kind of one which all Ring movies have, flickering picture, gray-scale and so on. I was probably around 10 years old at that dream, walking through a school yard, which felt ominously familiar. Well, I stumble and fall down. I try to get up, but I couldn't pull myself up. Something was keeping me down. I glanced at my hands, which were covered in dark, wet leaves and pulled one of them out of the leaves. It was covered in ants, swarming around it like black TIE-fighters.
And I screamed, but nothing was heard.
I woke up, wipe the sweat off my forehead and look at the clock. I get up, put my clothes on and open the window, only to see the whole city in ruins, with black orbs floating at the sky. And I thought "Shit, the dream is still going on.", finally waking up.
Thinking it afterward, it was pretty awesome.
