I've been reading alot about achieving lucidity in dreams and have noticed alot of people saying do reality checks so that you know that you are dreaming or not. I can understand this while you are conscious and awake. My question is how do you do this while you are dreaming (non lucid) because if you know to do a reality check then you must already bsomewhat lucid? And even if you did a reality check while asleep wouldn't your dream just make it seem real anyway? Sorry if I seem a bit naieve but I have never been able to do a RC in a dream, not intentionally anyway. In saying that I have had a couple of occasions where I become lucid because my dream was just to weird.
