Ghost Pictures: Pumpkin Spirits

We received these ghost pictures from Jakeysmomma and they appear to have a spirit mist hovering around them. Could a ghost have been with them, enjoying the Halloween festivities? You decide...

"My husband and I carved some pumpkins a few nights ago (10/14/06), and when we were done I went outside to take a few pictures with my digital camera. I was alone and was not smoking. Most of the pictures were fine, but when I looked at them later I noticed that three of photos had something strange about them. There was no smoke, fog, or mist of any sort on my porch when I took these. My husband and I live in a house that was a grocery store in the 1920's. We live in the upstairs where the family that ran the store used to live. I don't know if that could have anything to do with it. And for the record, I am not a believer when it comes to ghosts, but this made me wonder if maybe I needed to be a little more open-minded on the whole thing."
