Musicians, artists, writers or other creative people could benefit from using sleep communication. For example, artists could place themselves in a very special dream scenery (e.g., sitting on Mount Everest) and create wake world art by messaging their painting movements via an advanced brain-computer interface to the wake world, where it controls a prosthesis with a real paintbrush. Another exemplary future use illustration could be a musician,
being a fish with human hands within his dream, expressing his fish feelings and emotions in a “fish song”, which is transferred to the wake world using sleep communication with a very fine-tuned hand muscle EMG as body signal, which again controls a musical instrument.
The exemplary future prospects seem quite spectacular, and many more of these future prospects can be thought of. However, sleep communication has to be further improved in order to make these prospects possible. Especially, there is more research needed on which stimuli, body signals, and message coding schemes can improve sleep communication the best. Furthermore, more reliable methods have to be developed to induce lucid dreams.
You can design and create, and build the most wonderful place in the world. But it takes people to make the dream a reality. (Walt Disney)
