A vivid dream is like a free virtual-reality experience, no expensive headset required. While your body lies tucked up in bed, your mind can take you to exotic lands and introduce you to amazing characters. If you’re lucky, you might even be granted fantastical powers, such as the ability to breathe underwater or walk through walls.
I mention luck because it can often feel as if dreams are randomly generated – the day’s events might shape the narrative, but otherwise it’s usually a case of waiting to see what your brain comes up with. But it doesn’t have to be that way: in so-called ‘lucid dreams’, it’s possible for you to have a degree of control over what happens. This opens up many options for using dreams to your advantage, such as to rehearse for real-life events, generate ideas, or simply have a whole lot of fun.
Over at the lucid dreaming channel on Reddit, for instance, choosing to fly like a bird is a particular favourite. ‘All of a sudden I was soaring up into the sky and the most intense feeling of bliss, happiness and excitement took over my body,’ wrote one user. Another recalled flying ‘over the city, the deep blue ocean and even a bunch of islands’, and deciding to evade missiles along the way.
‘A lucid dream is a dream in which you know you are dreaming,’ explains Mark Blagrove, professor of psychology at Swansea University in Wales and the co-author of The Science and Art of Dreaming (2023). ‘As a result, you can either decide to simply observe the dream with the knowledge that it’s not real or you can actually alter the content of the dream.’
You might have experienced a lucid dream for yourself already. Research suggests that around half of us will have the experience at least once in our lifetimes. A quarter of people have them regularly. Whichever camp you find yourself in, there are various techniques you can use to start purposefully having more lucid dreams.
Reasons to lucid dream
Before trying out some of these techniques, you might be wondering if it’s safe and worth the effort. Note that, if you have sleep problems or mental health difficulties, lucid dreaming could make matters worse – so check in with a doctor or mental health expert first. If you’re good to go, there are a few enticing reasons you might want to give lucid dreaming a try. There’s some preliminary evidence that it will make your dreams more positive, thus improving your waking mood. Another small study found lucid dreaming to be associated with lower stress and higher self-esteem and life satisfaction. Most tantalising to me, though, is the idea that you could use your lucid dreams to practise skills that you need in waking life.
One researcher looking into this application is Daniel Erlacher at the University of Bern in Switzerland. Although he cautions that his investigations are preliminary, he and his colleagues have shown that people can use lucid dreams to practise a basic finger-tapping task, such that they improve as much as others who practised the task in waking life – by about 20 per cent. The research team has uncovered similar findings for darts and coin tossing. Commentators on the website Quora have claimed to use lucid dreaming to practise all manner of real-life tasks, including rehearsing musical performances, making speeches and preparing for awkward conversations. ‘I would recommend this to everyone who has lucid dreams, to use the dream state for practising sport or music or whatever,’ says Erlacher.
Other reasons for which you could use lucid dreams include to boost your creativity, for example by asking dream characters for their ideas. On his deathbed in 1920, the mathematician Srinivasa Ramanujan reportedly said he’d used lucid dreams to help him solve problems. Or you could try dealing with nightmares via what’s known as ‘lucid dreaming therapy’. The basic idea in the latter case, says Erlacher, is that, when you realise you’re in a dream, you confront yourself with the kind of nightmare content that’s been troubling you, be that a creepy house, a nasty person or something else. ‘You can go there and you can say: “Hey, what are you doing here? It’s my dream,”’ Erlacher says. ‘What people describe is that the nightmare disappears, usually.’ The more control you feel you have over your dream content, the more likely it is that you will benefit from this approach.
