Ghost talks and moves object

Ghost talks and moves object: Mom and I were sitting on the couch watching TV and we started hearing the ghost voice again from the vent. It's unbelievably creepy to hear that voice coming from the vent. And it's definitely a voice, not just some weird sound. Do you think it's the ghost? Or something else? A demon? I don't know. And what's it saying. Some people have said it sounds like a different language. Do you have any thoughts on that?
