The ocean in a dream tends to represent emotion on a scale bigger than you can fully hold -- its vastness makes it a fitting image for feelings that stretch past ordinary awareness. Calm water can reflect emotional ease, while a churning sea often names a feeling that's grown larger than you expected it to.
We ought not to use arguments or tedious discourses in giving judgement, much less flatteries, but only to pronounce what is known by experience and firm reason. - Cardan Girolamo (1501-1576)
