The Rainforest, Slowly Explained for Sleep

from Sandman Science Hosted by Sandman Science

Tonight, stand still under the canopy through one whole rainforest night - the dusk chorus, the world in a single tree, the rain that the forest makes itself, the glowing wood on the floor, and the dawn chorus before any light - narrated softly over calm music to help you fall asleep. Dim the lights, lower the volume, and let yourself drift.
