Revolutionary 'Halo' Device Enables Lucid Dream Control and Productivity

Startup Prophetic is developing a headpiece called the "Halo" that aims to induce and stabilize lucid dreams, allowing users to control their dream narratives. The device uses a combination of ultrasound and machine learning models to detect when users are in REM sleep. Prophetic has generated significant interest and booking revenue, with plans to deliver data in spring 2024 and ship devices in spring 2025. However, some experts remain skeptical about the practicality of converting lucid dreams into useful tools.
