Nightmares (Editing has stopped for now)

I have made a species called Shadows. I have made a subspecies called Nightmares. I made the Nightmares when I started watching r/morbidreality on YouTube and made these things. Each publish will be about one Nightmare, what they are like, what they do, and maybe a small story. (Most stories with the Nightmares are true stories, names of people have been left out due to respect)
