Is my best friend’s house really haunted?

Molly Asked: Is my best friend’s house really haunted?

I think my friends house is haunted because when i went to her house, we heard someone singing but we were totally by ourselves. 1 hour later i went to the bathroom and from the cabinet under the sink, i heard a voice say, " Carl, shes here!" in a raspy, guys voice. I screamed and ran out after that ( im not crazy, my friend heard it too!) The dogs were barking a lot and we heard footsteps. The other night she thought someone broke into her house because her door opened and closed and her dogs were going crazy. She heard a bunch of banging but the next day the doors were all locked andand the windows were intact. Her family didn't hear anything, only her. Should we use a ouija board?
