Ultrasonic Dream Expansion
Dreaming, engineered.
A headband that sends safe, low-intensity ultrasonic energy through the forehead and into the prefrontal cortex — gently pushing you into greater lucidity.

Two instruments. One target.
The core difference between the Dual and Phase is that the Phase is a more capable system because the ultrasound can be spatially controlled. This gives you more control over your prefrontal activity and in turn your dreams. However, the Phase requires more expensive components, more sophisticated engineering, and longer development time. Industry pricing data shows that ultrasound systems used in neuroscience and research laboratories can cost more than $200,000. Prophetic starts at $449.

02 — Intelligence
Superintelligence, in the loop.
The Phase's infrared neural sensors (fNIRS) read blood-oxygen changes on both sides of your prefrontal cortex while you sleep. An advanced superintelligence analyzes each side, plans a separate ultrasound pattern for the left and right arrays, verifies both against safety limits, then measures what changed.
- 01AnalyzeInfrared sensors read blood-oxygen changes in the left and right prefrontal cortex.
- 02DecideThe AI plans a separate pattern for each side: target, focus depth, amplitude and duration.
- 03VerifyBoth plans are checked against FDA intensity limits and each array's steering range.
- 04OutputEach array delivers its own low-intensity pattern, focused on its own target.
- 05AwaitThe blood-oxygen response takes a few seconds to build.
- 06MeasureThe AI measures the change on each side and decides what to do next.

The Phase can aim.
The Phase can spatially control the ultrasound focus. Instead of a fixed lens, multi-element phase arrays time each element so their waves meet at a chosen point — giving you more control over your prefrontal activity.
03 — Evidence
Our effect, measured.
Here's the effect of our modulation on dream experience. We've seen the largest effect in people who have difficulty perceiving or recalling dreams under normal circumstances.
- Q1How well do you recall the dream(s)? (1 - Very little 10 - Completely)
- Q2How vivid were the dream(s)? (1 - Very little 10 - Hyper)
- Q3How continuous were the dream(s)? (1 - Very little 10 - Hyper)
- Q4How clear was your thinking in your dream(s)? (1 - Not at all clear 10 - Extremely clear) Clear thinking means your thoughts are not irrational or deluded. For example, you understand that a dream figure is not really the same person as in the waking world.
- Q5I made deliberate choices that changed what happened (1 - Strongly disagree 10 - Strongly agree)

During stimulation we have recorded EEG time–frequency maps (event-related spectral perturbation, or ERSP). Warmer colors mean more power relative to baseline; cooler colors mean less. Across fronto-parietal channels, you can see a sustained increase in beta-band and some gamma-band activity after the stimulus, which is consistent with the fronto-parietal engagement we target for enhanced dreaming.

Here are testimonies from a few people who participated in Prophetic's 2026 Q1 beta testing. The technical prototypes they used were most similar to the Prophetic Dual.
Beta participants, in their own words04 — Mechanism
Your prefrontal cortex, gently rebalanced.
Prophetic induces lucidity by sending safe, low-intensity ultrasonic energy through the forehead and into the prefrontal cortex.
- 4.1TargetThis area of the brain is naturally downregulated during normal non-lucid dreams. And it is upregulated during lucid dreams.
- 4.2DeliverLow-intensity ultrasound travels through the forehead and into the prefrontal cortex.
- 4.3RebalanceWe help to rebalance this activity and gently push you into greater lucidity.
- 4.4YouAll you have to do is put it on, go to sleep, and have the most epic dream of your life.

05 — FAQ
Questions.
Is this a medical device?
No. The Prophetic Dual and Phase are not medical devices. They are not intended to diagnose, treat, cure, or prevent any disease or medical condition. Prophetic products are for healthy individuals aged 18 years and older and are for recreational use only. Prophetic does not provide medical advice.
Is it safe?
Yes. The Dual and Phase emit ultrasound focalized energy levels in the same range used on pregnant mothers for sonograms.
It does not implant anything into the brain, use ionizing radiation, or physically damage brain tissue. Unlike ionizing radiation such as X-rays, ultrasound does not cause cancer.
Do you put ads in my dreams?
No. Ultrasound cannot insert advertisements or scripted content into someone's dreams. Ultrasound neuromodulation can influence broad brain states or probabilities like attention, mood, or whether someone becomes lucid. It cannot transmit complex information, images, language, or branded content into the brain.
Can I trade in my Dual for a Phase?
Yes. We will have a trade-in program for the Dual and Phase. Details will be announced in the future.
