This is one of several photos I took of this particular area, and all the others are minus that strange, cloud like aberration you see in the distance in the center of the tree line. Strange as it may be, there is a cemetery right in that area. The other photos I took were all at the same setting, and the sun was behind the low dark clouds.
It's creepy and scary to some especially if they believe the ghost story right? You said the cemetery was right there.... I think that qualifies as it leaves something to the imagination of the viewer.
