I see what you mean. Indeed if RCing becomes a subconcious habit, like Breathing, it wouldn't make a difference anymore. You could end up doing RCs in dreams and not even noticing that the outcome of the check means you are Dreaming. And thus many Lucid Dreamers RC instinctively and not Conciously: as it is intended.

The whole idea behind RCs is becoming concious and aware so you can look at your Reality in an Objective, CONCIOUS way.

Perhaps it would help heaps if you First do some deep Meditation and Right after that, when you're still in the highly Concious Meditative state of Mind, proceed to do RCs.

RCs should be done very conciously indeed. It's not supposed to become an Unconcious habit, but a Concious habit ''implanted'' into your Subconcious, Dreaming Mind instead.

Great Point.
