Should I journal before bed or after waking up?

Techniques

Both can be useful, and they do different things. The morning entry is for capturing the dream itself before details slip — you lose around 90% of dream content within 10 minutes of waking, so that's where most of the recall value sits. Journaling before bed is a separate practice. A 2018 Baylor study found that people who spent five minutes writing a to-do list before bed fell asleep faster than people who wrote about what they'd already completed, because offloading unfinished tasks quiets the mental loop that keeps you up. Focused pre-sleep thinking can also steer what shows up in dreams: in Deirdre Barrett's research at Harvard, participants who spent 15 minutes on a specific problem before sleep dreamed about it about half the time, and roughly half of those dreams contained something useful. If you only do one, stick with the morning entry. But even a quick line at night about what's on your mind gives the morning entry context, and patterns get a lot easier to spot when you re-read later.
