Thats a really interesting idea APSJ, I must try that, in relation to your question my lucids generally start out as blurry as regular dreams but to increase their vividness I give a command like "increase lucidity now" basically expecting the dream to become more vivid generally makes it more vivid . If you want to get a quick fix I believe there is a drug you can get from the pharmacy, Choline something that increases vividness and dream recall, anyway good luck .
