I have to agree with gwendolyn and the others that once you start having LD's frequently that you don't usually want to stop. I can't always control when I have an LD, but I can control when I don't have one. I've went to be before and just told myself that I wanted to sleep and not have an LD, and not once has it failed me yet. I just have normal dreams, some of which I remember and some I don't.

If I could LD everytime I slept, i doubt I would miss normal dreams too much. Especially since when I LD I don't usually like to control the environment, I just like to play in the playground that my mind has created. It's very facinating and fun to do that.
