If you're having a dream though and realize you're dreaming then why wake yourself up? In your theory, you have to realize that you're having a vivid dream in the first place in order to wake yourself up, therefore you'd realize you were having a dream to begin with. So instead of trying to wake up, you'd either obtain lucidity right away or prefer a reality check! I understand what you were attempting to do here but it seems like it would just cause you to awake from a lucid dream and that's the last thing you want to happen. -Chase
