Weird woman

This is a story from when I was in the second grade. I was studying in my room. When I finished my homework and lay down on the floor, I saw something strange. There was a closet in my room that was integrated into the wall, and it was closed at the time. I was lying on the floor with my head facing that way, and yet something flashed in the corner of my eye. It seemed to be a pale, human right leg. It didn't look like something had fallen, and when I turned my head to look, I saw that a person standing. It was a stranger. It was a young woman, her head was bleeding, and her flowery dress was stained with blood. The door and the closet door were still closed, but someone was standing beside me. She walked straight to the wall on the other side and went right through the wall.  Of course, it didn't mean her break the wall. But I don't even think I dreamt it. This is the scary story I experienced.
