I've had some phantom sounds around the house that have woken me up several times, door slamming sounds, things like that. Unfortunately those can be explained away with brain science.
I know it isn't much help to your thread, but I'm honestly not sure that I would want to have a paranormal type experience. Seems like if you experienced something you'd be more sensitive for future shenanigans. I don't think I would want to open that can of worms.
