To my knowledge, no. If they do..then they are staying quiet about it. It makes me wonder though..If it is poltergeistic...and I do know that some poltergeists can appear in a simi physical/meta physical form, in rare cases or so i have read, that they can appear as shadows. problem being if it is a poltergeist in such a rare form then could the person who created it be draining energy or could the poltergeist itself be doing it?
corse that would be going on into theories and hypotheticals and such. a little beyond my knowledge. but still could it be possible?
The idea I'm trying to get across is that it might not actually be an entity, but yours (or someone else's) subconscious mind acting out.
I'm not sure if the experiences fit with that idea or not though. A clue might be found in whether these things happen when you or someone else isn't around.
