|Can such things be?|
|The Twilight Zone|
A poltergeist (German for "noise-making ghost"), when not taking time out of its busy schedule to make TV shows and movies, spends most of its time lurking in castles, ruins, old Southern plantations, attics, and basements. Anywhere people like a good story, some scary noises, and the odd wind rustle or two.
Poltergeists are very shy, so sadly have been reluctant to come out and play with scientists when they are visited by lab-coated intellectuals. Nevertheless, they do exist. Just ask anyone who makes money giving tours through old war fields, slave ships and abandoned or disturbed graveyards. Tour guides will assure you that the breeze you feel coming from the dank depths of a 10 foot deep hole has nothing to do with atmospheric homeostasis, but with the evil thoughts of the dead, near dead, and tragically murdered.
 Standard evidence of poltergeist activity
All of these descriptions come from people on the web or sites that detail what a poltergeist activity looks like.
- Noises, generally at night
- Changes in temperature
- Illogical fear or panic in the mind of a logical person, when nothing happened to cause it.
- Static or "foggy" images in pictures taken by auto-focus cameras (which never mess up, don'cha'no).
- Hissing or crackling noises in the background of otherwise straight forward home videos
- The "feeling" of being watched or touched. 
- Unusual or unexplained smells
- Children's toys being 'out of place' or broken (cause we all know our child would never break his or her toy)
