Why dreams are forgotten

Almost everyone dreams. Not everyone remembers, and the difference is mostly about memory formation rather than about dreaming.

The main reasons

• The brain state is poor at consolidating memory. Noradrenaline, which supports memory encoding, is very low during REM.
• Dreams are not rehearsed. A memory not attended to within moments of forming usually goes.
• Waking method matters. Sitting up, checking a phone, or moving straight into the day displaces a fragile memory almost immediately.

What reliably improves recall

The evidence-backed and unglamorous list:

1. Sleep longer. More late REM, more to recall.
2. Wake without an alarm where possible, or with a gentle one.
3. Stay still with your eyes closed for thirty seconds before moving.
4. Write it down immediately: the journal's quick-entry mode exists for this.
5. Intend to remember before sleeping. Recall frequency responds to attention and motivation, one of the better-replicated findings in this area.

Recall frequency varies between people as a stable trait, and it also moves. Most people who start a dream journal report remembering more within a fortnight.
