Empathy

Does any of this
sound familiar?

Most people who try lucid dreaming give up due to inconsistency and uncertainty about what actually works. Dreave is designed to untangle both.

01 / RECALL

You wake up and the
dream is already gone

That vivid dream vanishes the moment you open your eyes. It happens every morning. You want to record it, but there's nothing left to remember.

02 / HABIT

You tried, but
couldn't keep it up

You tried reality checks and dream journaling, but gave up before seeing results. You're not sure what the right approach even is.

03 / METHOD

You don't know
what to believe

The internet is full of conflicting advice, and nothing seems to stick. You just want a reliable method that fits your life.

Capabilities

What Dreave
can do.

Four approaches to build your lucid dreaming habit. Not a one-night experience — a system that compounds every night.

01 / NIGHT MODE

40Hz acoustic stimulation
at your 3rd REM cycle.

Just set your bedtime and Dreave automatically estimates your REM cycles. At the most lucid-dream-prone moment — the 3rd cycle, roughly 4.5 hours in — it quietly delivers pink noise and a 40Hz sine wave. Runs in the background while you charge your phone on your nightstand.

In v1.0, all features, including Night Mode, are available for free.
Night Mode Screen
02 / DREAM JOURNAL

Record by voice
the moment you wake.

Still half-asleep? That's fine. Just talk — your voice is automatically transcribed. Recall Score and emotion tags are added automatically.

Dream Record Screen
03 / REALITY CHECK

Daytime nudges that
grow dream awareness.

Just answer random notifications. The habit of checking reality during the day increases the chance of that same "Am I dreaming?" moment in your dreams.

Reality Check Screen
04 / ANALYTICS

Become a lucid
dreamer in 30 days.

Recall Score, Growth Index, and lucid dream frequency visualized in charts. In v1.0, all features, including AI-powered personal analysis, are available for free.

Analytics Screen
05 / COACHING

The app keeps
your habit alive.

Personal coaching messages appear on your Dashboard based on your recording streak and lucid dream progress.
8 milestones — first lucid dream, 7-day streak, and more — push you toward consistency.

About REM Cycle

Why 4.5 hours?

Sleep repeats in 90-minute cycles. The REM period of the 3rd cycle — about 4.5 hours after falling asleep — is the longest and most vivid dreaming phase.

Dreave automatically estimates this "golden window" and delivers 40Hz acoustic stimulation. Research suggests 40Hz stimulation is associated with gamma wave activity, potentially inducing brain states similar to waking consciousness.
