Wizards also sleep with their eyes open… well Gandalf did dunno if the residents of Hogwarts did! 😂

My mother had that . I was waiting impatiently for her to fall asleep so I could rest myself . It was almost one hour before I realized she’s not staring at the tv zombie-like but was asleep the whole time . Very SCARY

Rabbits (and most certainly some other animals) seem to sleep with open eyes. They have a second eyelid. This is to confuse predators to think they are awake.

Scout, have seen it in some people. Honestly, looks a little creepy.
