I noticed that after a while (though keep in mind this is a tad different from what you describe) of doing reality checks to become lucid in my dreams, they would stop working. The main one I used was attempting to push my index finger through the palm of the opposite hand and after some time of having much success with this method it altogether did not work - my finger would stop at the palm much like it would in Waking Physical Reality. Now at first, I was somewhat dismayed by this occurrence but after a while I realized that perhaps it was for the better as I would suddenly become lucid in dreams without any prior thought...it just sort of happened. This detracts a lot of the initial excitement felt with the achievement of lucidity, which in turn negated the undesirable effects of feeling the surge of emotion (rush in excitement leading to premature awakening from the dream)
So basically what I initially perceived to be a negative happening was actually something quite positive that has aided my non-physical development. A blessing in disguise, if you will. Never before had I really experienced the meaning behind that phrase in such a way that it directly affected me and I have noticed that while many aphorisms and famous quotes do have a semblance of truth to them, it is not until you experience an example of it from your own perspective that the saying truly bears weight. For this, I am grateful.
