Sleep paralysis is not the same as a nightmare... a nightmare is a scary dream, sleep paralysis is waking up but not being able to move for a bit.
This strange dream was not accompanied by sleep paralysis however that is one phenomonon that I encounter often. It was terrifying at first but now I can calm myself because I know it will pass eventually.
edit: I think this dream is a delayed reaction from the time you hit me on the head with the radio...
Nah, no way a dream about that would be nightmare for me

ahahha but yeah....i really liked the vividness in how you described your dream Cheesy you must have a crazy cool memory.
I'm actually very forgetful, however the things I DO remember I seem to remember in an insane ammount of detail. When I was very young, 3 and a half, I happened upon a large snake (turned out to be a rattle snake), ran to grandad and dad and told them I found a big bad snake. I still remember the event from events such as dad firing the rifle a few times then handing it to grandad frustrated, - then grandad shot it once and it was all over. I remember dad chopping the snakes head off, putting on gloves, coughing, then throwing the head into a trash barrel. I can still recall the event quite clearly, yet most any other memory from that time is almost a fuzzy nothing.
and then all of a sudden it was really dark and this anime girl fell out from the sky and then melted into a lake of blood and then i was in a schoolroom trying to get out of the attic and then the lake of blood was back and a guy was standing on one leg on a small branch sticking out of the blood and he was reciting the last testament or some other holy scripture like thhat
You should sign on to be a writer for "Grudge 3" since they are obviously in need of some different ideas.
You said, it seemed totally real and that your current life faded away (to paraphrase). Maybe it was real.
Thats almost what I think I'm afraid of - at least to some extent. Entering that dream felt more like waking up from one, instead of the other way around. I woke up confused as to how I got to where I was (which was my own bed) and it almost felt like falling into a confusing dream... except now I was awake for real.
I had a question though. When you saw yourself in the mirror, was it you, but not you? Or where you literally looking through the eyes of a stranger into the mirror?
I'm not sure what it was. It felt more like I was looking at pure evil if there is such a thing. If I could imagine pure evil physically manifesting itself I thiink that is what I saw in my odd bright black reflection.
For example, when you very first looked upon the liquid, you may have thought "blood" which led to the rest of the images because when you think of blood, that's what "you" invision.
I didn't think of blood at the time, that was more in retrospect recalling the dream. My feeling at the time was more of a river, except it was an enclosed tunnel with pulsating fluid stuff. It also looked now that I think back... a grainy blueish color. Grainy like old film grainy. Blue but more like a very desaturated blue. It was almost like a blue tinted black and white sequence.
I have weird dreams like that, too. But sometimes I actually know that they're dreams and choose whether to wake up or see them through. It's strange. =/
I've had dreams where I could wake up too, but this time I actually considered the fact that I was dreaming and almost disreguarded it as a silly notion. Weird...
"In the beginning there was only pure energy. Then, the energy realized it existed, 'I am.'
With the first thought, everything spawned from the energy to which it will all return."
Every once in a while I consider the possibility that a soul is the energy signature of a persons body. That this energy is somhow the source of our consiousness. Considering that matter is just a super concentrated form of energy, it almost seems possible. The potential energy in a human body is actually insane if you consider the ammount of energy in each atom - E=MC

E=MC
2 isn't exactly a recipe for a nuclear bomb but it certainly explains why one is scientifically possible.
