Noctilucent Eyes

If you find yourself surrounded by these, just say You'd Rather Not and get out of there.

These are eyes that glow in the dark. They can come in many different colors, but the two most common colors for Noctilucent Eyes are red and yellow. They also appear in different sizes and shapes, belonging to dangerous animals, most notably wolves or big cats. Noctilucent Eyes exist in real life and they're just as bright as they appear in fiction

Noctilucent Eyes can also belong to people who are in complete darkness although humans do not have noctilucence. They're just there to help us keep track of who's where in the darkness as we wouldn't otherwise know where they are.
