I want to make a story based game where the main character will pass out at some point. I have an idea of eyes shutting like you would see in movies and was wondering if anybody has any idea how to make something like that. I tested both darkness and blindness and neither give the right vibe. Failing eyes shutting i would gratefully appreciate other ideas to substitute this.

EDIT: thank you for the suggestions but i found part of the camera command that fades the screen out to black
