Nancy, thanks again for being such a great supporter and poster in this thread! Love you!
As for that dream about your mom, since she is emotionless in waking life, your dream tells you that she has feelings, wants, and needs that she does not show outwardly. She does wish for warmth and caring from others, and yet does not know how to express her own caring feelings for them.
Be sure to tell her you love her. I know you do. This is why, in your dream, you gave her your sweatshirt to keep her warm.
