This dream seems to be about approval from family and parental figures. If the breakup is recent, you might be seeking emotional support or permission from symbolic elders. At a deeper level, the dream is about your "inner mother," that is, about you own sense of right and wrong.
Interpretation is not possible without knowing something about what is happening in the dream. For example, dreaming of your ex boyfriend dancing with your deceased mother would be very different than if you dreamt of your mother cooking dinner for your ex, or of them arguing. The emotions that you experience during the dream are also important, whether you feel peaceful and content, anxious and fearful, or angry.
Love
She was saying god wanted her to be there. He needed her there in heaven.
This dream suggests that the dreamer feels that there is some unfinished business related to the deceased mother. Alternatively, the dream could be pointing out some important business or documents that have been mislaid or forgotten, and the "mother" represents the mature, responsible aspect of the dreamer's self. There is no need to impose supernatural associations to this dream.
This dream expresses your own grief and emotions surrounding your mother and her death. Seeing her "half-naked" suggests that you feel that she (her memory) was somehow exposed or dishonored after her death.
The dream suggests that you are living in the past. Your own mind is telling you that it is time to move forward into your own future and leave the past behind.
This dream seems to express your actual experience: your mother-in-law came into your life (with marriage) then she was gone (when she died.) The emotions felt during the dream itself might add more significance, as the dream could be part of the grieving process.
It means you are thinking about him
Dreams of the deceased are a normal part of the mourning process, and they can occur many years after the actual loss. The beach represents a boundary, which in this dream probably is the boundary between life and death. The end of the dry land symbolizes the end of life.
Assuming the question refers to a dream, it could mean that the dreamer is nearing the end of mourning and will soon be able to move on with life without overwhelming grief for the deceased mother.
Your mind is using the image of your deceased mother as a way of getting your attention. The dream itself suggests that you need to move forward with your life. Perhaps you are clinging to the past, and to your mother's memory in particular. Or you may be stuck in juvenile patterns of thinking and behavior. Other factors in the dream, such as the location, random objects or other people in the dream might provide additional clues. But there is enough information her so that the basic message is clear: you need to let go of the past and get on with your own life.
It is not clear whether the missing cat has been found in real life or not. If not, then the dream suggests that you might find the cat in a location associated with your late mother-in-law.
The devil is a symbol representing the personification of evil. So this dream suggests that the dreamer felt a sense of evil associated with the mother before her death. This might represent the disease that caused her death. Alternatively, it might symbolize the dreamer's anger, which in the dream becomes "projected" or misplaced onto the dreamer's mother.
A mother's concern for a child's well-being is often illustrated by the mother urging the child to eat their vegetables. So this dream expresses the dreamer's feeling the care and love of the mother even after her death.
