Possibility 2: Subconscious projection. Many psychoanalytic cases show that if you don't feel safe enough in infancy, it's easy to project your caregivers (mostly mothers) into female ghosts. In particular, many patients mentioned that they were afraid of the eyes of female ghosts. In your dream, you didn't look straight at the female ghost, maybe it was subconscious defense. It may be difficult for me to understand this. I'm not saying that you have to be mentally ill. At present, 80% people in the crowd have certain psychological problems, which is very common.
