Snakes sleep with their eyes open because they don't have eyelids (so it's not possible to close their eyes). The shark also sleeps with it's eyes open, while still moving around. Cows do that also. Some other reptiles do that to. To summarize it, many animals sleep with their eyes open.
Also, some birds and aquatic mammals have been shown to sleep with their eyes open. In all probability this is an evolved defense mechanism in response to the environment and nothing to do with the same thing in humans. Interestingly animals that sleep with one eye open actually do sleep with one half of their brain while the other half is still awake. Humans do not have this ability.
