A lucid dream refers to a dream in which the dreamer is aware that they are dreaming. Sometimes this means that they can control what happens in the dream, but simply being aware of being in a dream counts as lucid dreaming. Studies show that around 55% of people have experienced one or more lucid dreams in their lifetime. More regular lucid dreaming is much rarer. In fact, only 23% of people have a lucid dream at least once a month. However, it is possible to learn to take control of your dreams and there are even health benefits, as well as risks, associated with lucid dreaming.
