Choose your dream tonight.
A sleep-audio app built on published dream-incubation and memory-reactivation research. Not a white-noise app.
A 4-step nightly flow
Priming
A 3–5 minute story for your chosen dream, plus a signature sound cue and a spoken intention, played before you fall asleep.
Hypnagogic prompts
Your phone estimates sleep onset from motion and microphone sound level, then plays short, softening prompts. Sound files stay on your device and are deleted.
REM cues
Later in the night, your signature sound cue replays very quietly during your predicted or detected REM windows.
Morning check-in
"Did the sea appear?" Answer Yes, A little, or No, and see your check-in history build over time.
Seven dreams, four categories
Choose tonight's.
Calm
Soothing dreams: beaches, forests, gentle memories.
Adventure
Adventure-themed dreams, part of Dream Library Premium.
Thrill
Horror-toned dreams, age-gated with an adjustable intensity slider.
Nightmare Rewrite
Imagery rehearsal and sound cues aimed at reducing recurring nightmares.
Not guesswork
TDI
Sleep-onset (hypnagogic) prompting — the basis for Targeted Dream Incubation — has been shown in MIT Media Lab studies to produce themed-dream incorporation in a majority of prompted sessions.
TMR
Pairing a sensory cue with something learned beforehand, then replaying it during sleep, reactivates the memory — this is Targeted Memory Reactivation, the basis for the sound cue replayed during REM.
Nightmare Rewrite
Imagery rehearsal combined with TMR has also been shown to significantly reduce nightmare frequency — the basis for our Nightmare Rewrite category.
It raises the chance your dream includes your chosen theme — it does not guarantee any dream.
Wellness app, not a medical device.

Questions people ask first
Does it record me?
No. Only sound level is metered on-device; temporary files are rotated and deleted, and nothing is uploaded.
Will I definitely have the dream?
No. It raises the chance — results vary by person and by night.
Is Thrill safe?
It's 18+, opt-in, age-gated, with adjustable intensity. Skip it if you have nightmares or anxiety.
Is it medical?
No. It's a wellness app, not a substitute for care. See a professional for frequent, distressing nightmares.
