The meaning of Abandoned by parent / carer in dream | Dream interpretation
You may have a dream in which you are a child again and are being left at school, in a shop, in the street or park by your mother and running after her, perhaps not being able to reach her or not being heard. To be abandoned by a parent or carer in a dream—or to be separated from them so you feel lost and vulnerable—may represent a sense of not being wanted when you were young. This may not actually have been the case, but you may feel that way.
Alternatively, such a dream might also suggest that you are searching in waking life for the emotional freedom to be yourself and to be independent. On another level it may be pointing to your need to find guidance or help from others; many people have dreams of childhood abandonment after the death of a loved one.
If you are trying to attract your parents’ attention but they cannot hear you, such a dream may be saying that you feel neglected emotionally and you need to express your feelings and be understood by others.
