Lost mind and messed up orientation, waking up coldsweat.

So I've never understood why this happens, and it happens quite often.

Okay to begin, I should tell you, I don't dream like normal people, I do, but like very very rarely.
Once a week I probably do but I don't remember and,
They.Are.Always.Strange.
Either I'm at war with strange people, so I'm walking down with my cat among Tigers and huge, trust me when I say huge Lions, and then there is that particular dream, rather nightmare that wakes me up everytime,
But okay, lets get to the topic,
So yes, I wake up, I open my eyes and I'm forced to close them again, because the littlest of light in my room is too much for them.
Then I try to move my hands, and then when it feels like my body is perforated and all broken in pieces,
Limb after limb I can feel that stiffness, its fun at times but annoying when you need to wake up and do your work.
With all the power inside me, I have to move my body, and there it is, around 20-30 bones cracking, *crack* *crack* *crack*
And then the pounding of the head, So.Freaking.Hard.

And the worst part, I don't remember anything about the night before.... :|

So does this happen to any of you? =D Probably does.
