I hear what you're saying. I still believe the answer could be no cause I don't believe every thought in your subconscious is yours. It could have come from someone else, a commercial you saw, an outside source that you were completely unaware of. How many of people's thoughts are actually theirs, how many people actually think for themselves and not just store and regurgitate thoughts from outside sources? So even if it is your brain that stores this thought, it is quite possible that it is not YOUR thought.
