I was tucking my daughter in two nights ago and asked her if she had had anymore bad dreams. She hesitated but admitted that yes she had. I asked her what happened and after a pause she said she dreamt that I threw her down the stairs. At that point I started to cry. She gave me a big hug, and I asked her if she really thought I would ever hurt her and she said no. I told her she's right I love her very much and I would never hurt her. We stood there for a long time hugging and finally I tucked her in.
At that point I went in to my room. I sat there for a while in the dark and cried some more. My husband came in after a while and told me that I'm putting too much weight into a 7 year olds interpretation of her dream (probably true), that she's a great kid which he credits me for since he works so much (true) and that she loves me, and knows that I love her (true).
I don't know why she is having the dreams. I will admit I raise my voice more than I'd like. I have never physically hurt her or her siblings nor have I threatened too. I hope that with some extra hugs and positive attention her subconscious will catch up with the reality that she knows I love her and she'll go back to having happy dreams again.
