People have different levels of consciousness: the conscious state, the sub-conscious, and the unconscious. Dreams can be under one of those levels depending on the situation and the kind of dream. In the Philippines, people say that once a person is asleep and dreams about his teeth falling, it can be a sign that a person he knows (a family member, relative, or close friend) will die. To prevent the death that was signed or warned by the dream, the person should bite a wood upon waking up to transfer the curse to the wood. By doing that, the wood will die instead of the person.
