The term 'lucid dream' was coined by Dutch author and psychiatrist Frederik van Eeden in his 1913 article A Study of Dreams, though descriptions of dreamers being aware that they are dreaming predates the actual term. Eeden studied his personal dreams since 1896. He wrote down the dreams that seemed most important to him, and out of all these dreams, 352 were what is now known as “lucid dreams”. He created different names for the different types of dreams he experienced; each name being created from the data he had collected. He named seven different types of dreams: initial dreams, pathological, ordinary dreaming, vivid dreaming, demoniacal, general dream-sensations, and lucid dreaming. Frederick Van Eeden said the seventh type of dreaming, lucid dreaming, was the most interesting and worthy of the most careful observation of studies. Eeden studied lucid dreaming between January 20, 1898, and December 26, 1912. While describing this state of dreaming, Eeden said, 'you are completely aware of your surroundings and are able to direct your actions freely, yet the sleep is stimulating and uninterrupted. '
