That's an interesting concept.

If a real person (as opposed to anon who is obviously fake gay) has a significant dysmorphia or dysphoria, it kinda makes sense that external images of their body would be viewed as a different person potentially.

But it would take at least a minor dissociation like in the post. There would need to be that break in the mind of "knowing" that the image is of one's own body.

I don't have any kind of dysmorphia based on appearance, but I still take a second sometimes to recognize older pictures of myself. That kid isn't me in a sense, so there's a moment of disconnect while my brain says, "oh, wait, that's us"

Now, all we gotta do is line up some people willing to try it out and report back.
