I have had alot of these things happen to me as well and I certainly believe in ghosts. I believe some people are more in tune with it than others, and it has alot to do with certain places. I also believe dogs can sense things we can't. I have numerous pics from my IR game camera that I can't explain like strange lights that seem to be moving. The IR game cams are fairly new and I am curious if anyone else has had strange things on some pics.
