I keep seeing ghosts?

What you need to understand and ascertain is that some spirits are ghost, and some spirit do travel back and forth from other dimensions, the higher dimensional spirits usually would be nice, and may help you like a angel, and these higher dimensional spirits are harder to see all their details at times, and they know of their death, that they are dead. But ghost for most of them don't know they are dead, and it's easy for them to become confused. Now all the ones you spoke of do sound like ghost, except for the little girl, she may be a ghost, or she may be a imprint, not a ghost or spirit, residual energy that plays over and over again like a recorder.....many people get confused over the different type of haunts, and that's understanding....the more you experience these things the more you come to understand it and how they differ. You may see them all your life, you are sensitive to the spiritual world.
