How do I know that it's a poltergeist?

I think that I used to live in a house with a poltergeist. Well actually I'm pretty convinced. Things were always moved from the original spot and lights whent on aoff, but how do I know for sure that it is a poltergeist. What are some usual signs of a ghost?

well i gotta say it is the things movin around and bangs on my doors and walls when everyone else is asleep. the moving objects sometimes happens even when i am right there to witness it.

Is there a small child in the house? Classic poltergeist activity isn't an entity, but usually related to a child's unknowingly unleashed telekinetic abilities. Phenomenon can especially occur when the child is emotional. I'm personally convinced that it's related to a stronger form of the SLIDER phenomenon (Street Light Information Data Exchange Receiver...should be some links in various threads here....)
