I need a person who can tell me about mice behavior or ghosts or even levitation?

Alright, just now, I experienced the strangest thing in my life. I was asleep and sudden awaken by some loud cladding on top of the cage. I found my mouse up there, walking. no big deal. He falls down, walks a few feet, stretches a bit a levitates straight upward to the top of the cage. I swear I am not schitzo. I am just scared
