Verified step by step guidance

1. Understand that dreaming primarily occurs during the REM (Rapid Eye Movement) stage of sleep, which cycles multiple times throughout the night.
2. Recognize that REM periods lengthen as the night progresses, meaning the later REM stages are longer than the earlier ones.
3. Recall that the length of dreams is generally proportional to the duration of the REM period in which they occur.
4. Identify that the longest dreams tend to happen during the final REM periods, which occur closer to waking up in the morning.
5. Conclude that statements suggesting dreams are always the same length, or that the longest dreams occur during deep non-REM sleep or just as we fall asleep, are inaccurate based on sleep research.
