Being told who you should be
Imagine you lost your memory, had no memory of anything before a set day. You still have all of your basic functions, but you don’t know who you are.
Someone would have to tell you who you are, what you like, what you dislike, things that you do often, who you’re friends are, and what you do in life.
That would be mental. You would have no idea of who you really were for the rest of your life, I think I would go mental 😛
Just my thoughts from when the Bourne films got brought up in Media, it made me think.
