Hmmm yes I guess once masterd it would be the best way of getting aware when you are dreaming.. In dreams there is something different, a feeling. If you could train yourself to notice you are having that feeling or Not having the feeling of 'relatity'/awereness, you could make every dream a LD. ^___^

But maybe you would still need something to make you think: hey, I'am dreaming. It can't be on your mind constantly. That would drive you nuts =)

intresting =)
