IMO the easiest way to get vivid lucid dreams is to simply use techniques that involve a transition from waking life to dream scape without any lapse in conciousness. A DEILD or WILD tend to be the best dreams in terms of realism. The more aware you are in a dream the more real it seems. A DILD doesn't start as super realistic because you have to work your awareness up as soon as you become aware enough to get lucid where as a DEILD/WILD you already start off with full waking consciousness.
