Dream of child, died, mad, mother

My mother who has died sometime will visit me in my dreams. When she does she is usually always mad at me and acts like i am not her child. in my dream it's as if she is not dead, but lives in a different town and has another family. She wont say much to me, but always has the look of anger and disappointment. All i want from her is a hug and guidance, and to show me what to do
