Scariest thing that has ever happend to me

One of the scariest thing that has ever happen to me is when I went to Mexico. The whole family went and we all stayed at my grandma's house. I slept in one of the rooms by myself. It was calm at first, but after about a week or so, strange things started to happen. On one occasion, my bed shook at night. But the thing that sticks out to me the most is right after I got done eating, and as I stood, this lady in black walked up the stairs. No, I did not go check if she was still there. I just never slept alone again.
