You don't have to fall asleep alone tonight 🌙
Step into a quiet room where other sleepers have already tucked in. No chat, no accounts, no pressure — just company while you drift off.
A fan produces a broad, stable low-frequency wash with almost no variation. That makes it a very good mask for intermittent noise: voices in the next room, a dog barking down the street, a car passing outside. There is nothing in the sound for your attention to latch onto.
