In The Hiding Place, what almost happens to Corrie during a night of bombing raids?

I am assuming you mean the night that the Germans invade
Holland and the family is sitting around frightened by the sound of the
bombs?

In this case, Corrie eventually fell asleep despite
the commotion and she had a long dream which foreshadowed many of the events that would
take place after the German invasion.  She saw her family and others that she knew
riding in a wagon through the town square.  Her sister informed her that no matter what
this was a good thing as it indicated that things were in God's hands and he would guide
things according to his will.
