Normal, healthy sleep architecture includes all of the following sleep stages: REM, N1, N2, and N3.

1. REM (Rapid Eye Movement) sleep: This is the stage of sleep where most dreaming occurs. It is characterized by rapid eye movements, increased respiration rate, and brain activity.

2. N1: This is the first stage of sleep, also known as light sleep. During this stage, you're drifting in and out of sleep and can be easily awakened.

3. N2: This is the second stage of sleep and you spend more time in this stage than in any other stage. Your heart rate slows down and body temperature drops as you prepare for deep sleep.

4. N3: This is the third stage of sleep, also known as deep sleep or slow-wave sleep. It is the most restorative stage of sleep, during which your body repairs and regrows tissues, builds bone and muscle, and strengthens the immune system.
