Well, apparently sagittariuscraig there might REALLY believe he's from an alternate Earth that was transported from the Sagittarius constellation.

I don't know.

What I would believe is the case is it's another example of occultism making people insane.

All I do know is that Retconned is sketch af (par for Reddit), and I don't trust loonygecko there in the slightest.

Loonygecko claims that their own personal phone numbers changed due to Mandela effects...but that it's, yet again, impossible to document. And in Retconned you aren't allowed to question it. Oh no.

So, either liars, govt agents, insane, or a hodgepodge.

But you have to ask yourself what kind of person has a large human skull collection and obviously isn't a trained scientist (but has a profound interest in science). I'm getting those Ben Franklin Hellfire Club vibes man.
