Yes and play a couple of loops of Lucid Dreaming V2 before CR it will show you clearly in the dreams or the days after what is really being released from your subconscious mind as nightmares, remember nightmares are simply fears and weird info our subconscious has accumulated and buried deep and now is being released, perhaps one or some particular audios youve been working with are doing the job of pushing to the surface those fears etc.
That or your mind has been negatively stimulated while awake.
