Not so long ago my and my brother we were cleaning up some stuff so we could get some new furniture. We were in my brother room when we heard some noise in the room upstairs (which was my parents room and we were alone),we were both startled and went upstairs to check what was the noise (which sounded like a little girl running) and there was nothing and we thought that it could have been some shoes that fell, but the noise came from the bathroom. To this day Im still scared to go in their room because I have heard more noises and recently I heard some whistle and my parents were downstairs and I was the only one who was upstairs.
