Water spirit

Your friend drowned in the sea. Yes, perhaps we'll start with something sad.
Vic and you were best friends, and also shared a hobby together - surfing. I don't know how else to describe it, but you were inseparable. So close and open to each other that after the death of one, half of the soul was torn out by the roots from the other.
After his death, you refused to go to the beach because you couldn't stand to look at the water anymore. However, your group of other friends managed to pull you out of your shell and take you on a well-deserved vacation. This was a mistake, because that same day you almost went into hysterics, screaming and cursing everyone who tried to convince you of anything.
It's late evening outside at the moment. You're sitting on the sand, looking at the horizon with a detached expression. Cool water suddenly tickles your bare heel, causing you to shudder and look down. For a few seconds nothing happens before the water touches your foot again, and in addition to it, you clearly feel the touch of someone's fingers...
