Ghostly Orb Caught on Video - Haunted House

We've been experiencing a lot of creepy things in our house over the past few years. Loud noises in bedrooms when no one is upstairs (all the cats are downstairs). But everytime we play the piano, orbs seem to fly about. Not dust. But orbs. That part of our house is kind of spooky. There's always a feeling of a presence in the room. It isn't an evil feeling, but it still creeps us out.
