I'm baffled Most paranormal investigators will tell you all poltergeist activity is the result of RSPK, Recurrent Spontaneous Psychokinesis. Their explanation is reasonable--when the catalyst/person is removed, the activity stops. But in many poltergeist cases there are also classic hauntings, some interactive, some apparently residual. What makes it more plausible for a human being to psychically and unconsciously cause his house to burn, than for an unseen entity to do the same?
