When I was in 2nd grade, we were living with my mom's boyfriend in this ginormous house in Vallejo CA. One day while in the shower I heard what I thought was my mom calling for me. I kept yelling that I was in the shower, but the female voice kept calling my name. So I got out of the shower, found my mom and asked what she wanted. She said I must be hearing things.
Years later, as an adult, I brought it up and she said that she wouldn't tell me as a child, but the house was once a saloon/brothel and was haunted by some of the prostitutes that must have died there. Apparently a lot of people heard their names being called in that part if the house. Also, she said that on some occasions when they were doing drugs in the main room that had the staircase to go upstairs, they'd see ghostly women going up and down the stairs and thought it was just the drugs fucking with them at the time!
