I Wake Up An Entirely Different Person Tomorrow Morning?

Confusion reigns supreme!

I will be in an entirely unfamiliar room sharing a bed with a person I don't know! Whoa! Scary! Strange.... I may not be able to recognize myself!

Starting with a blank slate in my brain just like an empty computer memory, it will be an opportunity to invent my new persona. But it's gonna be a difficult task not knowing what to do and where to start.
