[Regal]

so guy got in accident and then can see a person's true personality. think it was a psychological and horror(not sure) help me find the title pls. pretty sure he told his friend and the friend helps him understand what a person's personality is based on what he saw. I remember he was talking to a girl and what he saw was leg spread and no underwear ( implying whore, I think) then there was also another guy with a face made of sand. thats all I remember. really appreciate if you can help
