It would depend on how this evolved in the water mammals researchers have found this in. Maybe some land mammals do the same thing, we just have preformed this type of experiment on them yet. If it does appear in humans, it'd probably be best to study those with extreme insomnia or people who claim to have very short sleep patterns (<2 hours a night) or maybe those who are narcoleptic (the other end of that scale).
