What causes 2 shadows of one item, and one shadow of the other things a few feet away from each other?

second light source for the additional shadow, and some shadows being drowned out by the light from one light source, with the other light source being too weak at that distance to sufficiently illuminate the surface to make the shadow it would cast discernible in the presence of the more dominant light source.

In addition to what @ragingloli said, one of the two shadows could be from a reflective source being hit by light from a singular light source, if there is only one.

What I wanted to know is what in the hell caused this mess all over my kitchen walls! There was no widow opposite this wall, and there was colorful crap on the same wall where the window is IN. And there are no other windows in there. It liked to drive me nuts.

Very interesting. Thank you.
