V.A.
When I was little-age 5-I had recurring nightmares about Godzilla. I got so tired of Godzilla winning and killing my family tht I rewrote the ending to the dream. I won then. Teach your little one how to rewrite while she is awake the part of her dream that causes the most distress. And, like any other medicine, repeat this procedure as often as necessary. Eventually the nightmare will depart.
