Professor Wiseman expects thousands of people to take part in an experiment in controlling dreams.
Participants will download a specially designed iphone app that turns their phone into a dream factory.
Placed on the bed ,the phone can monitor when a sleeper is not moving, which suggests the onset of
dreaming. It then plays a carefully crafted (精心制作的)"soundscape"designed to produce pleasant
scenes such as walking in the woods, or lying on a beach. The idea is that this will influence dreaming,
causing dreamers to form fantasyland inspired by the sounds they are hearing. At the end of the dream
the app sounds a gentle alarm to wake the dreamer, who submits a brief description of the dream to a
"dream catcher"database(数据库).
Prof Wiseman, from the University of Hertfordshire, who is best known for his research on sleeps,
said,"Getting a good night's sleep and having pleasant dreams promotes people's productivity, and is
necessary for their mental and physical well being. Despite this we know very little about how to
influence dreams. This experiment aims to change that. "
As many as 10,000 people are expected to take part in the study, declared at the Edinburgh
International Science Festival. Prof Wiseman teamed up with app developers YUZA, which created
the" Dream:ON" software. Participants will be encouraged to share their dreams via Facebook and
Twitter.
A national survey conducted for the experiment found that 21% of people had trouble sleeping
and 15%suffered from unpleasant dreams. Prof Wiseman said people feeling low dreamed far more
than others, and often had negative dreams. "Perhaps improving their dreams might help them,"he
added.
The "Dream:ON" app can be downloaded for free from iTunes or via the project site, http:∥
