This has been stuck in my head for a while and I wanted to get out.

This creature of the night has no name and no origins, it seemed to have popped into existence, I feel like this creature has been following me in the darkness...this is what I imagined it looked liked. It has a "White Female Mask" it wears on it's face, but I've never seen the creature without it so far. Two long tree bark like arms, on the left arm only two fingers, but on the right arm is three fingers. A long black neck that can extend to great lengths, while having long white hair across the top of the neck from head to shoulders. A body and tail covered completely in dark hair black as atramentous shadow. Long legs and hands(feet) as white as snow. It constantly hides in the shadows watching me, sadly I live near a thick forest. It's size makes it to the tallest trees in the world. I think it may have supernatural powers as but I can say that feel and odd feeling ever time I get a quick look at it.
