ghost; notice me

There used to be this old apartment complex right next to my school, all freshman classes used to go there. There was a huge amount of people who claimed to have seen a ghost and heard weird things, so I couldnt miss out on the oppertunity the time my at the time boyfriend asked me to go with him and his friends into the haunted house. This is my story, and you are the one to tell me what could've happened.
