I absolutely believe that the paranormal DOES exist, but I'm guessing that a large percentage of things that people classify as paranormal can be debunked (to borrow a word from a popular ghost hunting investigation team).
People often jump to conclusions and immediately label something unexpected as paranormal, instead of trying to figure out "normal" causes. It's important to observe (and document) details like weather, time of day, who's home, people's moods, etc., to try to find explanations.
