The title of this image is, "It's Yours"... For the moment. I sort of want to reference the idea that most alien abduction stories tend to involve magically winding up on a cold metal table (on a space ship?), aliens with scary medical looking tools bending over them, telekinesis calming their minds as they are afraid over the fact they are paralyzed and confused. Later, they realize they are missing time and the pieces they remember are scary and involved some unwanted surgery or pregnancy.
I was playing on the idea that to them, humans all look the same. Much like we would probably say the same about the aliens. So of course when they operate on humans they might mix up a head or two when putting them back on the body.
