so your mom and your girlfriend(just pretend XD) have switched minds. The only way to get them back to normal is if you "sleep ;)"with one of them. Who would you choose to "sleep ;)" with? Your mom with your girlfriends mind, or your girlfriend with your moms mind?
T: ....Neither of those sound particularly nice. Especially because I have a boyfriend and not a girlfriend. So it'd be like a complete stranger possession my mother.
J: How exactly would you even find out about how to fix it? And how did they switch minds in the first place?
