I can say in my experience, that having a peaceful and quiet mind greatly enhances the odds of having an LD, and increases our level of control. For me, every time I'd have touching and "homecoming" experience to God, I'd feel more fulfilled and peaceful, and it's on those nights that I have my LD's the best.

My point being, that having a calm and happy life in the waking life is pretty essential to having great LD's.
