I had a nightmare where there was this monster-like lady who was sitting on my bed (don't remember her exact look), I was passing by my bedroom to reach the kitchen when I see her, thinking it was my mom. I enter the room, the woman's evil head turns 180 degrees to look at me, and I step back. The woman's demonic eyes crossed in a way NOT possible in a human being. I was so frightened, and the woman attacked me. Before she got to me, I woke up.
Then a few years later, I got the same dream, but I attempted to out cross her eyes, but I failed. Then she launched herself at me, creepily. Then I woke up, not that scared, but weirded out!
