People in my flashes are clothed

On those rare occasions I get a visual flash on something, I don't see it through the other person's eyes. Believe it or not, I see it through their skin. My brain is an image converter and I remember one time imagining this womans's naked butt up-close. On her right rumpcheek was the shadow of a hand. Execept it wasn't a shadow. It was actually the hand. There has to be space between bodies for this to work; if there is skin to skin contact then all I see is black. My guess is it has something to do with the electrical field surrounding the body - more often than not the people in my flashes are clothed.
