Nightmare

I dreamt that I was at the beach right next to my house. Wind and rain white cap blue waves lighting and water spouts. I tried to climb the sand dune cliffs but kept on sliding down. The undertow then pulled me in and I started to drown. I woke up in the bathtub then quickly I got out. I've had that dream before I wonder what it means, probably dont smoke a joint and decide to go bathing.
