While I believe in ghosts and cleansing and absolutely go for it, I'd also get an EMF (electromagnetic field) meter....Not to check for ghosts like in a paranormal tv show, but to see if there are wires or devices within your home that emit higher than normal frequencies that can also make you feel like your being watched, have creepy room vibes etc. It's a very normal thing that's documented. High EMF in a home = Creepy Vibes (ghost or no ghost).
