What makes dreaming so much fun is the realism of the dream experience. When we are in a dream, it can appear as real as our waking life but without the constraints of physical rules as dreaming isn't a physical system rather it's entirely cognitive where the mind is rendering out a virtual reality for us to have 'what if' scenarios. And yes we can fly, teleport, walk through walls, simulate anything limited by our imagination and skill while in this medium of self-expression.

For those who develop and participate in their 3-5 dreams, they get to have a second-life experience with different perspectives and experiences you'll never have while awake because you are dreamer. The architect of your own dream experiences.
