I suppose, it would be a dream that might have had something to do with a book about nazi concentration camps, I read before going to sleep, even though I read nothing similar to my dream.

I dreamed I was in a middle of a huge swimming pool filled with blood instead of water. I was standing on the water surface (well, blood surface in my dream) with only the upper of my body, and nothing under the blood surface, I had nothing lower than my waist.
I was trying to scream for help, but no sound was coming out.
Anyway, at some point I managed somehow to run ( more like to float) out of the swimming pool, and I was suddenly in the yard of my childhood house.
In my trying to escape from an unknown enemy, I started to float in the yard. But I had to be very careful, as the yard was filled with sharp, long, metal spears impaled in the ground.
When I looked down, I noticed I had no more body at all, not even that upper half I had before, and now I had only the head with only a bit of neck attached.
I started to float, carefully between the spears, trying to not get impaled my head in one of them.
But in the end, when I was so close to the yard gate, my head got impaled in the last spear.

Of course I woke up at that moment

Tell me one of your dreams!
