Lucid dreaming has been used for centuries for various purposes. Some believe in Astral Projection, where the dreamer can leave his or her body and visit distant locations on Earth or in space and time. Others believe that lucid dreaming is a method of communication in which the dreamer can receive messages from somewhere else. Some people think it's just plain fun!
Lucid dreamers agree that these experiences feel vivid, the senses are delighted, and the mind has some degree of control over the transpiring events. So what is stopping you from harnessing this innate power to compose music without the boundaries of waking experience?
No distractions. No nagging voice of doubt. No need for polished, dexterous mastery of an instrument. Your mind is the instrument. Your soul a receiver. Your brain an interpreter.
Give the world the gift of your music. Give yourself the gift of creation in a dream-state.
