That's a kid under the blanket near the center...
The ghost explained here.

...sorry about the quality but I still wanted to post this one. The conditions were
extremely dark, being in a cave and all, so the shot was taken at ISO 800 and underexposed
by 0.7 to get 1/5 sec. shutterspeed.

Taken at Yemrehana Kristos Church just outside of Lalibela, Ethiopia.
