This is another one of my favorite episodes of the show, this is a rather interesting one almost a bit of a Philp K Dick like tale. The concept is terrifying when you think about it, just to one day wake up and realize you whole life is just gone in an instant. We're in the same boat as the protagonist as we're trying to figure out what the heck is going on while David is trying to prove in vein, he is who he says he is.
Throughout the episode you constantly asking questions in your mind, did David (if that's his real name) when he drove back home from the wild party did he inadvertently drive right into a portal that took him into an alternate world or is he in some sort of virtual reality program and the settings just suddenly changed and whoever is running it forgot to erase or reconstruct his memories.
I do like that there is a bit of philosophical territory on our perception and what truly makes and determines one's identity. We see David interacting with this psychologist who sounds like he's been taking a lot of his own meds, as he gives David a talk down about people that are insane whom think their one person or another. But this conjecture is incorrect as the doctor is talking about self-deluded people that want to believe a famous figure in the present and history but also schizophrenia for some other cases.
David has neither of these illusions as he's a person that knows who he despite the little proof he has; it really show that no one can tell you who you really are nor can any hard proof as both aren't reliable and can be deceptive, only we can determine and decide who we are.
The ending will give you a chill as it let's just say it's one of those that makes you just like David, more lost than before.
