Do you believe in spooks, as in ghosts?

The building I’m in right now is supposed to be haunted, especially the two floors right above me. I’ve heard heavy footsteps, strange noises, laughter, crying, etc from time to time. Also, today the door at the end of the hall has opened and closed four times, but no one has walked down the hall. Do you believe in spooks? And I don’t mean this in any racist way, which is one meaning I came across when looking this up on google.
