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.

Now do that in front of a mirror
