I have a story about seafoam...

I've only been to the beach once in my lifetime. But as bright and busy as it was, it remained my favorite place. In my dreams i would visit there in the dead of night and talk to the many who stood on the shore, or sat and let the waves wash over them. I can remember them all having interesting names but i could never retain any of them. I never saw the same person twice and at the end of each dream after a nice conversation and a new friend had been made, they would have to leave. I would wave to them as they entered into the ocean and lay down creating a bed of sea foam in their wake, until finally they'd dissappear but the seafoam would stay. Today i heard my brothers friends joke with him about the ocean saying things like "don't touch the seafoam or you'll be covered in mermaid." I didn't understand what he met until i looked it up. Turns out when mermaids die the turn into seafoam and float on top of the sea becoming one with the waves.
