Question 4

conclusion

Answer 4

• Dreams occur during REM sleep only. Dreams reported from NREM sleep are from previous REM episodes.
• Estimated dream duration and REM period lengths are very similar, thus it shows that dreams are not instantaneous events but rather experienced in real-time.
• Eye movements correspond to where, and what the dreamer is looking at in the dream, hence, it explains that they are not random events.
