Ghost Experience

During my stay at my cousins house last fall break my cousin and i had a ghost experience. We were in his room playing xbox and we heard a weird noise down in his basement. So, being the curious teens that we are, we went down to investigate we went down and saw nothing and heard nothing. But later that evening we were home alone and we heard something walking on the hardwood floor behind and by the window stood a shadow of what looked like a woman.We ran screaming like little girls! & the sounds and noises continued for the rest of the stay. It was the scariest time of my life.
