Amongst the DILDs that I've had, some have been really vivid, like my first ever LD, whereas others have felt like just a fragment. The vividness of the dream is linked to how aware you are of the dream, and how many details in the dream you're paying attention to. To increase your awareness, you can stabilize more in the dream, and try to notice as much of the dream as you can. I think that the reason WILDs are sometimes more vivid that DILDs is because the mind is already aware when you enter the lucid dream, whereas the awareness must be gained in a DILD.
