Well. If you go around not answering your question, I see a possible scenario:

You never complete the RC in a dream. So, basically, you ask yourself when in a dream "Am I dreaming?" and then go on to get distracted, because you never decided that yes, you are dreaming.

Main point is that, whatever you do in waking life, RC-wise, is exactly what you will do in a dream. If you do not answer your question in waking life, then you will not answer it in a dream, and your state will not change.

Consider that a counter hypothesis.

Good luck though.
