The team designed over 40 themed soundscapes that mimic environments, all of which are free to download. They range from a peaceful garden with birds chirping to the Wild West with drinks flying at a saloon and horses neighing in the background.
“The first ones were designed to be relaxing, such as the nature soundscape, or somewhat strange, such as the city one,” Professor Wiseman explains. “We then asked about 1,000 people to describe their perfect dream, and based the additional soundscapes on their replies—that was the basis for the flying one, the zombie attack, and shades of grey ones.”
The study showed that the soundscape you listen to has an influence on the emotional tone of your dream. For example, the nature-based soundscapes create dreams that are especially positive, while city-based soundscapes produce more bizarre dreams.
