A study launched today (April 10th) will assess whether an iPhone app could give people the dream of their choice. Whether it's a walk along the beach or a woodland trip, sounds could help give people a tailor-made experience while they lie sound asleep in their double beds. Professor Richard Wiseman, a psychologist from the University of Hertfordshire, teamed up with app developers YUZA to create the software for the app. Professor Wiseman's research kicked off at the Edinburgh International Science Festival where he began collecting thousands of reports from the app's users in order to assess its effect on their dreams. Dream:ON, the name of this new app, aims to improve quality of sleep and overall happiness by allowing people to choose the setting of their dream. Users could wake up feeling refreshed and more satisfied than usual. The app works by detecting a lack of movement in the sleeper - which means they are entering a dream state- before playing the requested sounds. The study's creators are hoping that social networking sites Facebook and Twitter will provide a platform for Dream:ON users to share their experiences with the app. Professor Wiseman said: "The app is free and we want as many people as possible to participate, I have conducted many mass participation experiments in the past, but this is by far the most ambitious and exciting."
