When my mother put me to bed she always said sweet dreams. Then once when I was in my teens and I had gone to her room to say goodnight she forgot to say it and I had trouble going to sleep. She always said it so I figured she was mad at me and I didn't know it. I asked her about it the next day and she said no she wasn't mad, that she didn't know why she didn't say and that I should have said something right then. To me sweet dreams was part of her saying she loved me when she put me to bed.
