Very clear dreams

Does anybody know if chanting "Om" while falling asleep enhances dream clarity? I have been doing so for the past two nights and my dreams are crystal clear, though not lucid. What's more, when I wake up I find myself mulling over my dreams and the dream recall lasts throughout the day. Could the chanting be responsible for it?

I've never heard of this before. Ha ha. How exactly do you go about doing it? Just chanting "Om" before you go to bed? I've been looking for ways to make my dreams clearer because they always seem distant and foggy when I recall them.
