Is my house haunted? please help!?

It's a possibility. I don't know for sure, but there are tons of paranormal investigators and a lot of them do it for free. You should google some in your area. I know how you feel because I have crazy stuff happening in my house too. Ignore the people who say you are crazy and find out what's going on. Also, you may want to check the history of your house in the archive files at your local library. You may find some interesting stuff.
