The Hide And Seek Ghost

My brother and I were going to spend the night at our best friend's house. It was a week before Halloween. Every time we spent the night at our friend David's house, we always stayed up late. It was about midnight when we went outside to play hide and seek. My brother and I ran to the back of the house and found a shed that David didn't know about. David was the seeker like always. As we were waiting for David, we saw a shadow at the other end of the house. It shouted something at us and started running to us. I went to the opposite side of the shed waiting for what I thought was David. It finally made it to my brother's side of the shed, so I ran out into the darkness. I realized that my brother wasn't following me. I went back to the shed to find my brother standing by the shed, staring into the darkness. I asked him if anything came back by him. He said no. He also said that he saw a shadow circle around two times and disappeared. It was odd because we both saw the same thing, but it did different things to both of us. As soon as we realized something was wrong, we ran back to the house. As we came to the front door, our friend David jumped out and scared us even more. We told him that we saw something back there and he said he saw something, too. We never saw anything else that night, or to this day forward.
