I had a brain surgery around 5 years ago because of epileptic seizures. I'd try to find out how the operation went and how long I've been sleeping/was in coma and if i still had seizures but most of all i would be horrified how much my brain made up because my house also burnt down around 4 years ago and i had to move and start a whole new life.

So the short answer is: I'd probably be in absolute shock that none of this ever happened. I'm pretty sure i would have some sort of existential crisis.
