3 HOURS with the sound of thunder and rain on BLACK SCREEN

With the sound of the rain, a kind of camouflage is achieved. The brain is offered a stimulus that creates a sense of control, a repetitive pattern that convinces it of the absence of external threats. The sound of running water, such as a stream, rain, or the sea breaking on rocks, is relaxing. More and more studies show that the sound of water has a relaxing effect on people. It stimulates the brain and seems to have a positive effect on memory.
