When I was about 9-10, I used to have this recurring dream. I would be lying in a partially darkened room because I usually had a nightlight on somewhere or my blinds open. But at the time it seemed dark. I would dream that I had fallen asleep (which I had) with my left arm hanging off the bed. I would wake and realize something was watching me. I knew it was behind the cracked door. So, I would stare at this space behind the door. Out from behind this door, walked a black cat, with huge green eyes. I didn't have such a cat at the time. He would seem friendly and casually walk towards. When he was just beneath my arm, he would lunge and attack my arm. I would wake up. This dream occurred for months. It happened the same way, every time.
