Scientists 'able to induce lucid dreams'

12 May 2014 Last updated at 11:41 BST

Scientists in Germany have found they can increase the number of lucid dreams "the majority" of people have, by sending weak electrical signals into the brain.

Michael Nitsche, professor of clinical neurophysiology at Gottingen Graduate School, explained that during these lucid dreams it is sometimes possible for the dreamer to control the plot.

The researchers hope their findings may be used to treat mental illness and those who suffer from disturbed sleep.
