There have been several occasions when people I know have either seen a ghost or experienced their presence. On one such occasion, a friend told me that she woke up one night and she heard an unusual noise coming from downstairs. First, she waited in bed and listened intently to the sound. She didn’t hear the sound for a while and then she heard the sound again. She thought it was someone talking.
After waiting a little while, she went downstairs and looked around the house. No one was there. She also looked out the windows and no one was outside. When she went back upstairs, the door to her bedroom was closed and she had left it open. She knew it was a ghost.
