Its just a dark figure. And like, every time I wake up in the middle of the night its always there. And I can't help it cause I can't wake up with my eyes closed. Keeping the lights on doesn't help either
My mate reports similar things, its being stuck in between a dream and a waking state. He also gets sleep paralysis. Its a strange thing, but he has learnt to enjoy it. Certain drugs make it worse, specially stuff like Amphetamines, and deffinately Mephedrone.
But its not necessarily a bad thing. Salvador Dali used to sleep on a chair with a metal spoon in his hand, and a metal pan by his legs. Soon as he nodded off he dropped the spoon and woke up. He did this to capture all the surreal dream state images.
I would overcome your fears of what you see, this will give you more control over it. Fear is a loop of thought, trapped in that box all you will see is the corners of the box
I have never once seen anything weird when I woke up. Its like *ping* the world appears and I`m there. Back into reality. Never ever got caught even slightly in between. My dreams are a whole other story though, I just come out and enter the same dreams over and over again. Almost flashbacks from dreams. Weird how people differ
