You're in a lecture hall giving the talk of your life, when you suddenly become aware of the fact that you aren't wearing any trousers.
Embarrassed, you look up to see if anyone has noticed, only to be met by a sea of three-eyed aliens. Do you continue your talk, fearing the repercussions for your career, or do you say to yourself: "Hang on, the only way this could possibly be happening is if this is a dream. Let's just jump on that passing flying banana and go and have some fun."
If you're more likely to do the latter, then you are a lucid dreamer. During your nightly adventures, your brain detects you are in a dream because events would not make sense otherwise. Researchers at the University of Lincoln have discovered that this ability to pick up on logical flaws in your dream-world translates into a talent for spotting hidden connections and inconsistencies in the real world, leading to greater insight and problem-solving skills.
Dr Patrick Bourke, Senior Lecturer at the Lincoln School of Psychology, says: "It is believed that for dreamers to become lucid while asleep, they must see past the overwhelming reality of their dream state, and recognise that they are dreaming.
"The same cognitive ability was found to be demonstrated while awake by a person's ability to think in a different way when it comes to solving problems."
Lucid dreaming could be a sign that you are an insightful person when awake. Not everyone experienced lucid dreams. In order to investigate the connection between our sleeping and waking minds, the researchers examined 68 participants between the ages of eighteen and 25, ranging from frequent lucid dreamers to those who had never experienced the awareness of being in a dream state.
They were all asked to solve a collection of "compound remote associate" problems designed to measure insight. In this type of test, subjects are presented with three words and asked to find a fourth one that forms a new compound word with each of the initial words. An example would be the words "age," "mile," and "sand," for which the solution is "stone."
Participants who frequently experienced lucid dreaming solved 25 per cent more of the word association problems than the non-lucid dreamers. The cognitive skill involved in solving this particular kind of problem has previously been linked to insight and creative problem-solving, leading the researchers to believe that the same processes which alert us to the façade of our dream-world help us make sense of reality when we are awake.
