While sleep may seem like a steady state, it actually consists of 5 stages that cycle throughout the night. There are 5 stages of sleep including the REM (rapid eye movement) stage. A complete sleep cycle takes about 90 to 100 minutes and a regular sleep consists of 4 to 5 complete sleep cycles.

The researchers found out that many of the participants in the research had actually sleepwalked. Some of them did so more than once that night, for a total of 32 sleepwalking episodes.
