Bodies of water — lakes, streams, oceans — are frequently connected, in literature and experience, with moodiness or meditation. Characters near the sea, or near rivers, are found to be lost in reveries, daydreaming, thinking up poetry, or otherwise listening to their muses. The water is connected in some way with a lifting-up of our attentions away from the visible.
What do you see? — Posted like silent sentinels all around the town, stand thousands upon thousands of mortal men fixed in ocean reveries…Yes, as every one knows, meditation and water are wedded for ever.
— Moby Dick, Chapter I: Loomings
Attached here are examples of this peculiar connection.
