Adriana Lara sent in this Winchester House ghost picture from the Winchester Mystery House...
"I took this picture at the Winchester House in October 2005. Not sure what it is, please review and let me know what you think. I took it while on the tour of the mansion...it was taken at the garden that was supposed to be Sara Winchester's favorite part of her garden that she tended to herself. Please take a look and shine some light to what it looks like to you."
This very well could be an apparition. It is strikingly similar to other apparitions we have seen in ghost photos before...often times they do not have definition of details.
What is interesting is the rainbow effect in the upper right, without the presence of moisture.
