Nightmare man

my dream and I call him Nightmare man and here’s how it all began. I was often stressed and had nightmares from time to time but I thought nothing of it, I played it off as usual nothing less. After nightmares, the dreams became more and more frequent and one thing I started to notice was the same man I never met was in all my nightmares I was shocked after I realized, the man I know call nightmare man is tall has cold black eyes, and the widest creepy smile I have ever seen. In all my nightmares he never says a word just stares in my soul from my window oh and it’s on the top floor of the house that’s what makes it so scary. I always wake up from the dreams in sweats but somehow freezing maybes it’s him? or maybe I just have an overactive imagination? I don’t know anymore but he scares me none less I wish he would just leave but now I see him when I’m awake not just in my nightmares...
