Sleep spindles occur during stage 2 of the sleep cycle. Here are the steps of the sleep cycle:

1. Stage 1: This is the lightest stage of sleep, the transition phase, where you feel yourself drifting off.

2. Stage 2: This is still a light stage of sleep, where your heart rate and body temperature drop. This is the stage where sleep spindles occur. Sleep spindles are sudden bursts of oscillatory brain activity generated in the reticular nucleus of the thalamus.

3. Stage 3: This is a deeper stage of sleep, where you become less responsive to outside stimuli. It's harder to wake up from this stage.

4. Stage 4: This is the deepest stage of sleep, also known as REM (Rapid Eye Movement) sleep. This is where dreaming occurs.

5. Then the cycle repeats itself.

So, to answer your question, sleep spindles occur during stage 2 of the sleep cycle.
