Dream:ON is the world's largest dreaming experiment.

Since April 2012 millions of people from around the world have signed up to participate using the Dream:ON app to record their sleep patterns. The app has been playing themed soundscapes at the optimum moment during the night in an attempt to influence the topic of the dream.

Sleep scientists have been analysing the data and have strong evidence to suggest that men have much more sexual dreams than woman, and that the full moon might even have an effect on the intensity of our dreams.


Dream:ON is a collaboration with well-known psychologist Richard Wiseman.

Richard launched the app with a flurry of media interviews at the 2012 Edinburgh Science Festival. The reception was stunning with over 300 international news outlets covering the story in the first few days. The likes of CNN, Wall Street Journal, Daily Mail and Fox News all did profiles of the app which spawned a surge of downloads.

By April 2014 the application had recorded over 13 million dream reports; a hugely valuable data set for scientists to analyse trends across a range of demographics from around the world in a controlled test.



In Summer 2012 the BBC's One Show did a 10-minute segment on the app and the science behind it.


Dream:ON achieved a Top 10 ranking of all apps on the iTunes App Store in its first week after release.


2 years after the experiment began, the results of the Dream:ON experiment were published in prestigious scientific journal New Scientist.

How It Works

The Dream:ON app has a wide range of themed 'soundscapes' for users to download - from 'Peaceful Garden' to 'Space Shuttle Launch', there's something for everyone.

Before going to bed, users set a soundscape that matches something they'd like to dream about and then place their device on the corner of the mattress. During the night, the accelerometer will measure tiny movements in the bed. The app analyses these to determine at what stage in the sleep cycle the participant is at and plays the soundscape at the most appropriate time - i.e. when the senses are most alert to audio and the person is most receptive to subconscious suggestion.

In the morning users are asked to record a 'Dream Diary' so that data can be gathered on whether the soundscape has worked.
