What if you could wake up inside your dreams — and take control? Ad Somnia guides you into lucid dreaming: the extraordinary moment when you realize you're dreaming while still asleep. In a lucid dream, the impossible becomes real. Fly over cities, revisit forgotten places, meet anyone you can picture, or simply wander landscapes that exist nowhere but your own mind. Ad Somnia is built to make these experiences easier to reach — and to repeat, night after night. HOW IT WORKS Ad Somnia eases you into sleep with calming audio, then works quietly through the night. Using subtle Apple Watch vibrations timed to your sleep stages, it sends gentle cues designed to spark awareness inside the dream — without pulling you awake. Over time, your mind learns to recognize these signals and carry that awareness into the dream itself. WHAT YOU GET • Gentle sleep onset — drift off to calming, sleep-friendly audio • Smart Apple Watch cues — subtle vibrations timed to your REM sleep • Awareness training — short nightly pre-sleep sessions that strengthen your ability to go lucid • Unobtrusive by design — cues are crafted to guide, not wake • Build the habit — turn lucid dreaming from a rare accident into a repeatable skill WHY AD SOMNIA Lucid dreaming is a skill, and like any skill it grows with practice. Ad Somnia pairs a calming pre-sleep routine with precisely timed cues so every night moves you closer to your next lucid dream. Start your session tonight. Fall asleep peacefully. And let Ad Somnia guide you toward your first lucid dream. — Ad Somnia is intended for relaxation and personal exploration. It is not a medical device and is not intended to diagnose, treat, cure, or prevent any condition.

Lucyd is built on Targeted Lucidity Reactivation (TLR), a method developed by sleep scientists at Northwestern University. In their 2024 study, ordinary people using a smartphone version of this technique went from 0.74 to 2.11 lucid dreams per week, nearly three times as many. HOW IT WORKS Train by day Short reality checks pair a signature sound with one thought: "Am I dreaming?" Optional reminders keep the habit alive through your day. Cues at night Start Pre-Sleep Mode on your nightstand. During the REM-rich part of the night, Lucyd softly replays your cue, timed and volume-ramped to reach the dream without waking you. Journal every morning Speak or type your dream the moment you wake. Lucyd keeps your voice recording, transcribes it, and reads it for recurring dream signs, the personal patterns that tell you "this is a dream." WHAT YOU GET • The full TLR training protocol, automated every night • A morning journal with voice capture and transcription • Dream-sign detection that runs on your phone • Insights: lucidity trends, sleep correlations, recurring signs • Reality-check reminders tuned to your schedule • A home-screen widget that keeps your cue close PRIVATE BY DESIGN No account, no sign-up.
