Some authors support the theory that the unconscious is warning us through dreams about a possible incubation of a disease, or some organic weakness. But others point out that the dream shows us a need for affection and care. There is also a curious and old theory referred to dreaming that a family member gets sick. If in the dream the relative is the parent it may be a prediction of some disease in our head. If the mother gets sick, the disease will be in the belly. In the case of a child, it will be the heart that gets sick and if the brothers or sisters are sick our arms and legs are in danger.
