Not everybody can be the best figure skater in the world. Only one person at a time can. Similarly, not everybody can be the most skilled lucid dreamer in the world. However, I strongly believe that every person has it in him/her to be able to majorly control their environments, perceptions, sensations, and behaviors in lucid dreams. Dream details are what you are thinking when you are in the dream state. So if you can think it, you can experience it in a dream. It does take practice, but I think almost everybody is capable of it. It is nowhere near as difficult as advanced figure skating.
