Like you get transported into an alternate universe where everything is almost same, but with tiny differences. The world looks normal to everyone and you’re the only one that have memories of the differences.
Do you think you would trust your memories or would you think you lost your mind?

If you’re not going to lash out or try to reverse it somehow, I guess that’s a perfectly healthy way to look at it.
