Dream Library: Dream Incubator

Choose your dream. We help your brain get there.

Dream Library is a sleep-audio app built on one idea: the dream you fall asleep wanting is more likely to be the dream you have. Pick a dream from our library, and Dream Library guides your brain toward it, from the moment you close your eyes through your REM windows overnight. This isn't a relaxation or white-noise app — it's dream targeting, built to raise the chance tonight's dream includes your chosen theme.

HOW IT WORKS — A 4-STEP NIGHTLY FLOW

1. Priming (3-5 minutes, before sleep)
A short narrated story for your chosen dream plays while you're still awake. It plants a signature sound cue — say, gentle waves and a soft chime — and ends with a spoken intention: "Tonight, I will find myself by the sea."

2. Hypnagogic Prompts
As you drift off, your phone estimates sleep onset from motion and microphone sound level, then plays short, softening prompts tied to your dream. Sound-level metering creates temporary recorder files locally; they are rotated and deleted on a best-effort basis and never uploaded.

3. REM Cues
Later in the night, your signature sound cue replays very quietly during your predicted or detected REM windows, reinforcing the dream association.

4. Morning Check-in
When you wake, Dream Library asks: "Did the sea appear?" Answer Yes, A little, or No, and add a one-line note. Your recent seven-day check-in score summarizes those responses.

BACKED BY SLEEP SCIENCE

Dream Library is built on published sleep-science research, not guesswork. Sleep-onset (hypnagogic) prompting — the basis for Targeted Dream Incubation (TDI) — has been shown to produce themed-dream incorporation in a majority of prompted sessions in MIT Media Lab studies. Pairing a sensory cue with something learned beforehand, then replaying it during sleep, reactivates the memory — this is Targeted Memory Reactivation (TMR), the basis for the sound cue replayed during REM. Imagery rehearsal combined with TMR has also been shown to significantly reduce nightmare frequency, the basis for our Nightmare Rewrite category. In short: based on TDI and TMR research, Dream Library increases the chance your dream includes your chosen theme — it does not guarantee any specific dream.
