I have been doing RC's asking "Am I dreaming?" for sometime and have experienced few results. I have given much thought to this and created a hypothosis to possibly address my problem.

Hypothosis:

During waking life the subject asks "Am I dreaming?" and concludes "No, I am not dreaming". Because dreams are mostly made of 'day residue', this carries over to the subconcious mind and the dreamworld. Therefore, when the subject is dreaming they ask, "Am I dreaming?" and subconciously conclude, "No, I am not dreaming". This results in no lucidity or an almost lucid dream.

Now, if we change the wording of this question to, "Am I awake" and conclude "Yes, I am awake" this should carry over to the dreamworld so when we are dreaming we will ask, "Am I awake" and conclude "Yes". Now that we have concluded we are awake we proceed as though we really were awake. At some point we should notice something very strange about this 'waking' life and be joltted into lucidity.
