New phone app for 'sweet dreams'

Scots are among the least likely in the UK to have the proverbial sweet dreams, with just 25% telling researchers they enjoy a pleasant sleep.

Prof Richard Wiseman is leading a project using mobile phone technology to try to find the reason why.

The 'DreamON' phone app monitors a person 20 minutes before they want to wake up, with a "soundscape" designed to invoke pleasant scenarios such as lying by the sea or walking in the countryside.

They will then be asked to record their final dream.
