A modern bedroom bathed in soft, ambient lighting, where a person sleeps peacefully with a sleek, non-invasive brain-computer interface gently attached to their forehead. On the nightstand, a digital screen displays real-time data on sleep stages and dream content, synchronized with a health tracking app. Surrounding the room are bottles of REM sleep enhancers and 'sleep biotics,' their labels reflecting advanced gut microbiome research. In the background, a holographic display showcases a personalized sleep program, combining pharmaceuticals, brain monitoring, and brain modulation devices. The atmosphere is serene yet technologically advanced, hinting at the ethical debates and societal impacts as millions embrace these sleep optimization technologies.
