WhatshallIcallmyself: Show me some proof or supply some theory as to what these things are that we can test and let's go from there.
That would be a waste of time for both of us. There is an overwhelming volume of evidence for the existence of poltergeists and other paranormal phenomena. There is so much evidence, both experimental and anecdotal, that an entire branch of science is devoted to collecting and studying such evidence; it's called Parapsychology. If you are sincerely interested in Truth rather than scientific orthodoxy, then go to your local library and dig in.
But of course, for fundy materialists, none of it is valid evidence. And parapsychology is a pseudoscience at best. All 'evidence' for psychic phenomena has been deliberately falsified, or there was some flaw in the experiment, or bias in those who were conducting the experiments.
Parapsychologists regularly get dismissed and ridiculed by orthodox scientists who fear that acknowledging the existence of paranormal phenomena could legitimize the claims of religions, which, ironically, is a great boon to religious and occult charlatans of all stripes because it means that the realm of the paranormal will remain the last refuge for mysticism instead of being de-mystified like all other natural phenomena have been.
