My dog spotted some ghosts!

Sometime last summer our new puppy started barking and running in and out of our bedroom. We didn't really think much of it, but it continued for a few minutes. I got up to see what she was doing and I didn't see anything in the room, but she was barking at the ceiling. We believe our house is haunted, so I grabbed my camera and started to take some pictures of the ceiling and the rest of the room. The photos here show some orbs. The one is actually behind the mirror, and they are all taken from different angles.
