Dream of mother, children, mad

For the past 3 years I've been having this same dream in different situations since my mother passed away.She has been coming to me in my dreams the same way majority of the time,in all white,jet black hair flowing,floating above me in my bed.My mother would be crying or may be extremely mad.Than my children crying out for me not to leave them,My husband is always in all my dreams trying to protect me from getting hurt
