In a dream, if a woman sees that she is observing a waiting period, it signifies worry, misery and confinement, or illness and the divorce that requires the waiting period — unless the waiting period in the dream is that of widowhood, in which case it signifies irrevocable divorce, or the death of the husband, the child, the mother, or whoever she mourns, for whose sake she gives up comforts, perfume, soft clothing and the like.
