Our brain is capable of everything, the problem really is not if our mind can do it or not, but if we will be able to control that "ability" in a conscious way.
For me dreams are spontaneous and unconscious representations of a random scenario and many times not, which in certain cases we see as visions or "videos" but undoubtedly represent a creative factor extremely brilliant, so get to develop the ability to control that part of our being would be extremely fantastic, especially for those like me are not so creative.
Yes, i believe.
