I never heard of sleeping with a light on, but if it works for you then keep doing it heh. For me, the dreams I remember the most vividly are when I wake up momentarily and fall back to sleep straight back into a dream. I do recommend you try keeping a dream journal if you are looking into increasing your dream recall.

Oh yeah, you should check out the forums of the link I posted. There is a section to increasing vividity or lucidity of your dreams by consuming certain foods before sleeping.
