Symbolism of swimming pools
Swimming pools, and immersion in water, was dominant throughout the film. We see scenes of Claire in the water, swimming, soaking, dangling her feet, Nina's son visiting and being excited about using the pool, Claire making herself go into her dead son's room to pull his swimming trunks out of storage, etc. The imagery of the swimming pool is a repeated motif through the whole film.
Did anyone else notice this and also wonder about it? Anyone have ideas on what the symbolism was?
