Mind racing at night?

Drift is a drug-free sleep aid for insomnia and sleep anxiety — built around cognitive shuffling, a science-backed sleep technique developed by cognitive scientist Luc Beaudoin. It helps you fall asleep without medication and stop overthinking sleep when calm apps and stories haven't worked.

The method: a calm voice whispers one neutral word at a time. Mushroom. Lantern. River. Your brain does gentle sleep visualization — a bedtime brain trick that turns each word into a fleeting image. Before long, those images blur into micro-dreams, and you're asleep. Many people experience something close to sleep in seconds once the loop starts.

No meditation experience needed. No content libraries to get lost in. No sleep tracking. Just one sleep hack, done exceptionally well.

Why it works

When you're anxious or overthinking, your brain loops on coherent, stimulating thoughts — plans, worries, replays. Cognitive shuffling interrupts racing thoughts by flooding your mind with random, unrelated, emotionally neutral imagery. This mimics the brain's own natural transition into sleep, signaling that it's safe to let go.

In a published study, participants using cognitive shuffling fell asleep just as quickly as those using evidence-based journaling techniques — while lying in bed, with zero effort.

Sleep for an anxious mind — including ADHD sleep

Drift was designed for people whose minds won't stop: insomnia driven by worry, sleep anxiety, and neurodivergent sleepers who need a different rhythm than slow meditation. If you've tried white noise, sleep stories, and meditation apps and still lie awake staring at the ceiling — this is different. Cognitive shuffling works on Night 1.

Cognitive shuffling (serial diverse imagining) was developed by Luc P. Beaudoin at Simon Fraser University. A 2016 study of 154 university students showed it reduced presleep arousal and improved sleep quality — and it's been featured in the BBC, Fortune, CNN, and The Guardian.
