Player One Syndrome

The feeling you get when you can no longer distinguish a tangible understanding of reality, you feel that you are at the centre and nothing else is real, like you are player 1 in life and that everything else only exists when you are there and that other people are only NPC's (Non-Player Characters).

I think I'm suffering from Player One Syndrome I cant tell what is real, like I'm Player 1 in my own video game.
