The Rhythm of Sleep
Why do We Sleep?
Not all animals sleep, but like humans, those that do have powerful sleep needs. For example, dolphins must voluntarily breathe air, which means they face the choice of staying awake or drowning. The dolphin solves this problem by sleeping on just one side of its brain at a time! The other half of the brain, which remains awake, controls breathing (Jouvet, 1999).
Hallucinations can occur and feeling of falling.
NEED TO KNOW:
