Part of ADA IS vigilance. I get what you are saying about your standard RC getting meaningless but there are ways to do it in a manner that gives it more meaning. For example, your riding passenger in a car down a highway near the coast, you look off to the side of the road and see a bilboard with a seafood advertisement and there is a giant crab on top of the bill board. obviously the logical side of your brain will tell you the crab is fake, but ignore that. notice it, notice that it is not normal, its weird, it out of place, ect. and assume you are in a dream, i mean where else do you see odd giant crabs? question your reality, get a sense of everything else around you, and then do a RC. basically, you question anything that seems very weird, or out of place. convince yourself you actually are dreaming, and your job is to PROVE it with your RC. the reality check may not even be used in the actual dream. in my last lucid, I saw a flying picture, determined it was way out of place, and knew i was dreaming. maybe you dont want to be constantly aware all day, but train yourself to recognize weird things when you come across them and question them until your sure you are dreaming or awake, after all, dreams feel just as real as reality, why not check? hope that helps!
