images in minoraty report

There were images in the movie "Minoraty report" thats significant value like water. Like in the begining of the movie it shows a holligram of his family and son at the beach. Also how Anne Lively died the old man forced her to drown. And how the PreCogs lived in the water and they could see in the future. They used the water to explain alot of things in the movie. Especially when the captain took the precog out into the real world and she couldnt reallly survive w/ out water. They were at the mall and she knew it was about to rain she was pretty excited to feel the rain on her skin. It seems like water was is in the beggining of every scene but everybody see's the movie in their own perspective. To me it seems like that as if water was very important in this movie.
