Stage 1: Light sleep; easily awakened; muscle activity; eye movements slow down.

Stage 3: Considered deep sleep; difficult to awaken; brain waves slow down more, but still have occasional rapid waves.
Stage 4: Considered deep sleep; difficult to awaken; extremely slow brain waves.

Breathing is more rapid, irregular, and shallow. Heart rate and blood pressure increase. Dreaming occurs. Arm and leg muscles are temporarily paralyzed.
