What does it mean to see the grim reaper in a picture?

I was with my friends at Wendy's and my one friend began taking pictures of us all. She posted them on facebook and in a particular picture (I was in mid-word with my hand flailing with a gesture, my friend across the table talking too) I recognized a figure to be out of place. At first I thought it was a trash can but then I realized that it was the height of the jeep next to it. I looked at it closely and it HIGHLY resembles the grim reaper, or what we believe him to look like. I kept staring at the picture, I tried to tweak it, make it higher resolution and easier to see, and it was even more prominent than before... Is this supposed to mean something?
