I think my house is haunted. I hear footsteps sometimes, I have heard doors slam when I was home alone, and tonight, I heard footstepts and people talking. I have heard the footsteps and other noises before, but tonight was the first night I heard the voices,(which sounded like my daughter and her boyfriend talking), but when I went to check, they were both gone. I am not afraid and/or scared of ghosts, but I just want to know how to communicate with or understand what the ghost might want from me.

Try recording them and see if you get anything. A digital voice recorder and leave it out when you think it is going on. You can even ask them to say something into it. Also document the times things are occurring and keep a log book. Look for patterns. See what evidence you can gather.
