The unregenerate; uncharacteristic of any literal interpretation
Dreaming that you are a bastard in the true sense of the word suggests a feeling of loss or disownment in relation to your family in particular your parents. Possibly you have allowed yourself to detach from your parents and now are finding a need to reconnect. Making the first move is recommended to reignite a sense of family. Forgiveness may also need to be considered so as to enable you to create a new relationship with your family or parents.
