Imagination is the humans biggest enemy

I can't sleep again. I am too scared what will happen after I turn around and close my eyes. I am too afraid of what will happen if i eventually fall asleep or just if i seem like i am asleep. I am too terrified to even move after i cover myself up with my blanket up to my head. No one takes me serious and thinks it isn't anything. But I imagine things I wish I would not..
