Dreaming of a dead relative, especially a mother, indicative of how much a person misses her. How one interacts with one's mother in the dream may have different meanings, depending on the mood in the dream.
It is generally believed that a dead relative speaking to a person in a dream represents that individual’s intuition. This may be especially true if the mother is offering advice. If the mother is angry, it may reflect a sense of disappointment with how things are going in the dreamer's world. It is not unusual for a pregnant woman to dream about her deceased mother. This type of dream may be caused by anxiety in the pregnancy or guilt for gaining too much weight.Seeing a dead mother as evil represents a person's negative choices and attitudes. The evil is part of an intuition into possible negative outcomes in the future. In a dream, mother’s may offer unwelcome advice or guidance or represent frustration within the dreamer.
Often seeing a dead relative in a dream doesn't represent anything more unusual than seeing a live relative in a dream. In general, the happier one is in one’s life, the more positive dream experience, even when dreaming of a deceased loved one.
