Why You Remember Your Dreams — and Why You Don't
Dreams occur primarily during REM sleep, which comprises about 25% of your total sleep time. While everyone dreams, not everyone remembers their dreams, and this doesn't necessarily indicate better or worse sleep quality.

Research suggests dreams primarily support emotional processing, helping us work through challenging experiences from our daily lives. During REM sleep, the brain forms new connections and recalls experiences, allowing for unconstrained problem-solving and creative thinking.
Key factors affecting dream recall include:
- Anxiety levels before bed
- Medications
- Sleep disorders like sleep apnea
- Gender (adolescent girls tend to remember dreams more)
- Personality traits (creative individuals often have better dream recall)
Tips to improve dream recall:
- Stay in the same position for 90 seconds after waking
- Write dreams down immediately upon waking
- Keep a dream journal by your bed
- Consider foods rich in vitamin B6 (poultry, fish, milk, bananas, spinach)
Research has shown that REM sleep helps reduce emotional reactivity to negative experiences over time. One study found that participants who experienced full REM sleep periods showed less emotional distress when viewing negative images after two days compared to those with limited REM sleep.
While hitting the snooze button might increase dream recall due to an additional REM cycle, sleep experts don't recommend this practice as it disrupts healthy sleep patterns. Instead, maintain a consistent sleep schedule for better overall sleep quality.
Remember: Dream recall often occurs because you've woken during a dream, not necessarily because you've had more REM sleep than someone who doesn't remember their dreams.
