I was at a beach and I saw big waves coming so I had a towel on my hand and I used it to fly, I flew over the first wave and then taller waves came, and I kept flying on top of them, ¬¬ and they kept on coming bigger till I woke up.
On 'Hitchhiker's Guide to the Galaxy' they say you should always know where your towel is... and it definitely helped you here!
