Here is a 2 picture composite that were taken with an iPhone one after the other in a restaurant called Monties in Tempe Arizona by my son who at the time worked there as a waiter. It was late during a slow time in the unused area.
The picture shows a ghost walking through the wall from left to right.
On the left picture, look down the hall and slightly lower than middle left ( of hallway )you will see the start of a white something.
On the right picture, the white shape has walked across to right hand wall. You can see the lower legs up to the waist. Make the comparison of looking down the hall from pic 1 to pic 2 and in pic 2 the scene is blocked by this shape which to me seems like a man carrying something.
