A few weeks ago my girlfriend and I were sleeping together, when I woke up to her saying "What are you doing?" She sometimes talks in her sleep, but this sounded so coherent and urgent that it jolted me awake and I asked what she was talking about. She then woke up and said she thought she saw someone at the end of the bed. Thinking it was just a dream, or semi-awake hallucination, we thought nothing of it and went back to sleep. About an hour later, I woke up and saw someone standing on the bed, with the sheets wrapped up and twisted to their neck. I didn't know what do but the first thing that came out of my mouth was "What are you doing?" My girlfriend then woke me up. I had been dreaming the exact same thing that she did, and said the exact same thing.
I know it's the power of suggestion or whatever, but fuck that.
