A forthcoming device called Halo, expected to launch in 2025, is designed to help users achieve lucid dreams. By stimulating the brain during sleep, the device aims to enable users to control their dreams, offering potential therapeutic and recreational benefits.
Lucid dreaming involves being aware of and controlling one’s dreams, with up to 70% of people experiencing it at least once in their lifetime.
