Not Everyone Can Lucid Dream?

Mr. Bowen brought up and interesting point today. He said that it may be that not everyone is cut out to be able to lucid dream. I started thinking about it, recalling what Professor Helene Porte told me. She said that lucid dreaming rarely comes naturally to people and that it is definitely possible to train oneself to be able to lucid dream. This is proven by Stephen LaBerge, the leading researcher on lucid dreaming, whose subjects have taught themselves to lucid dream.
