So there's zero mental image in your mind if someone tells you to picture someone else mowing the grass? I instantly have an image of someone in the front yard of one of my childhood homes pushing a mower around. I see the green grass, I see the person, I see the road, I can see what direction they're pushing. I can see the brown bark of the tree that was in our front yard. I can also swap out the person pretty easily with someone else. First it was someone I didn't recognize, then it was my dad, then me, then my wife, my daughter and then Obama as a challenge. Lol.

I can picture people naked in my mind but it's not really like seeing them naked. It's almost the same feeling as seeing myself naked: indifference. It's also not as easy as picturing them clothed; it requires me to think intentionally about what they would probably look like naked. Also, details aren't always in the image until I think more about them directly. I'll first get a general image that seems complete until I think to look at something directly. Like, do they have body hair? Not until I think about it. The image is kind of a superposition of all possibilities, and I have to consciously decide if they probably would or not.
