I dreamt me having what I'm assuming is a good dream, nothing outstanding, until I saw a black silhouette of a woman, with half of her upper body peering at me from behind a door or a wall. I keep looking at her, she hides, then she appears again. I knew it was a woman because I saw an outline of long hair and I knew she was looking at me. I never had dreams like this before so I was a bit concerned.
