Answer:
One night, Anne wakes up everyone in the attic with her screams.
She's had a nightmare about the Nazis coming to take her away.
It seems totally normal to us that her fears would manifest in this way, but everyone in the attic short of her parents seems more than a little annoyed by this.
Mr. Dussel even locks himself in the bathroom; he's so angry.
We see Anne's parents concerned and helpless for their young daughter who has to deal with the ugly realities of war and death.
They are afraid for her as well as for themselves.
Anne's request for her father's comfort after the nightmare, rather than her mother's, provides more fuel for a conflict that appears to be escalating.
Mrs. Frank's feelings are extremely hurt, and Anne knows this but can't figure out how to make things work with her mom.
