Wow, that is a classic ghost picture.
I used to volunteer at a boyscout camp in California when I lived there, and this camp literally WAS haunted.
For one thing, underneath the archery range were three human skeletons with no heads. Creepy, I know.
Then there was this really cool adobe. We all just called it the old adobe, and I never knew the real name for it. But there were too many legends about it to count.
This is my favorite legend about it, and like all legends the facts are fuzzy, but all show the same picture.
The adobe was built by monk(s) who were trying to bring religion to the native americans that lived there, so they made the adobe. During this time, there was a rainstorm and one of the rooms collapsed. They never repaired it. Later, men came and for whatever reason, killed one of the monks. Some people told it in their story that he didn't beleive the right things, or that he commited a sin or just made these new guys really angry. Whatever it was, they killed him.
To stop the other monks from doing whatever the first guy did, when repairing the damaged room, they put his bones in some of the bricks.
Much later in time, a woman was staying at the adobe. One morning, when she woke, there was a man dressed in monks clothes muttering verses from the bible. She ran out of the room half naked and when she and a few others came back, he was gone.
My father, in 2007, while walking to the campmaster trailer said he saw a lantern inside. It was moving and he was about to go inside to scold whatever cubscout was inside, but when he made a move towards it, the light went out. When he and the ranger went in, there was no sign the light was ever there. Oh, and in California there are no fireflies.
So, as an activity, you could earn what we called the Ghost Hunter Patch. You had to either sleep in the adobe for one night or go out to the archery range until midnight snapping pictures. People brought disposable cameras and digital, and no matter what, at leats two or three of the pictures had the same eerie white smoke you have in your picture. And no one was allowed to smoke cigarettes, the camp was in the middle of the desert and the activity was done in the summer, so there was very little change of fog, and no flashlights were allowed, because they "scared away the ghosts". All the cameras had flash, so in Ranger's explanation, the ghosts didn't like flashlights, but when the flash went off on a camera, they would be caught in it too late. When I'm on the right computer, I'll post my favorite pictures. Either way, I've beleived in ghosts since
Oh, and I've heard of a legend of a seaman who was sailing up cape cod, and it got so cold that other men were offering to take turns. But he said no, and everyone stayed down under the deck in their rooms. When the storm subsided, they came up and found thta he was still alive, but his hands were dead and frozen to the wheel. So they had to cut them off, and they brought him down to his cot. He died, and when they got back up to the deck, the hands were gone.
Maybe a similar legend goes for your foot
