Psychologically: In this state one runs by the blustering surf and by flowing out rain, is as 'filled' by the moisture as from an intensive feeling of happiness: Here it is less about profound symbolism - rather around superficial euphoria because the dreaming has met just 'the love of his life' and has a bath now 'in the sea and the dear waves'. One dives quite deeply and would like to drown 'in the luck'... wakes till one.
