Strange dream about seaside...?

I had a dream where i was at the beach with my parents. i was six years old in the dream. it looked like a lovely old movie, in sepia with shots of the family being happy. There was a rock pool and some of my fathers friends were sat in it (it was like a jacuzzi) and they all had a glass of champagne. the suddenly, after seeing lobsters through the crystal clear water my mum and dad are sucked through the water and disappear, (sepia ends here) and i swim underneath but i cant see them. i keep swimming until i am in the deep blue. and then i woke up. i have no particular fear of oceans, lobsters or my dads colleagues. help?
