EDIT: Note that these are childhood nightmares.
At first glance, I thought they were real.
My childhood fear was probably the dark and my imagination. There was a nightlight outside the bathroom down a little corridor pretty close to my bedroom but it still didn't actually light up most of the house. When my mom went to bed, the house would be entirely dark if not already. I usually dreamed of these nightmares with vampires
inb4twilight and zombies. It usually creeped the stuff out of me because I usually have to go to the bathroom or get a drink in the middle of the night.
