Where was Sophie hiding bfg 20-24?

In "The BFG" by Roald Dahl, Sophie was hiding in the BFG's cave during the scenes in chapters 20-24. She was initially frightened but soon learned that the BFG was friendly and not like the other giants. The cave was filled with jars and bottles containing dreams, and it served as a safe haven for Sophie as she befriended the gentle giant.
