Have you heard about orbs? In a long line of silly paranormal claims, orbs are in the pantheon, the top shelf, the upper ethereal reaches of silliness.
The idea is that when you take a picture, you’ll sometimes see little fuzzy circles in it. The obvious conclusion is that these are the souls of the dead.
I mean, c’mon! What else would they be? Out of focus dust grains that are floating in your field of view? Don’t be silly!
