Not really that scary, but an odd sort of haunting

Is it possible for a toilet to be haunted? A la Moaning Myrtle? Because I think mine is. It keeps making weird glurging noises at random moments, and starting to run and then stopping again. I will walk in to check on it and the water in the bowl will be splashing back and forth, as if the whole thing has been violently shaken. If a whiny pre-teen ghost comes out next, I’m moving.
