An idea for experiment

its for LD masters and its reccomended they are married\gf\sleeping with someone :)

next time you try LD, tell your gf\wife\person you sleep with to try and contact you by voice or touch (gently, so you won`t wake up) and see if it penetrates to your dream :)

i think you have to be really good at ld for that because you need to be sure youll have a lucid dream while they try to contact..

Erm, I dunno if it's what you are looking for but I once had a lucid dream whilst listening to a half of nfl, I know the NFL was in the real world because the dream commentary I heard corresponded to both the highlights and the score.
