Why Do We Sleep in Cycles?

Examples

1. You fall asleep, dream for a while, wake up briefly, then go back to sleep, like playing with your favorite toy twice before bed.
2. Your brain takes a short nap in the middle of the night so it can keep working on your dreams later.
3. Sometimes you wake up at 2 a. m. because your brain is just taking a break between cycles.
