Dream Eighteen

There are three, or maybe four of us in a small seaside resort. We are comfortably talking among each other and wandering around the small shops and whatnot. After several hours of this, we end up wading in large pool... or maybe it is part of the ocean. There is a concrete, tile covered wall separating this pool from other bodies of water. The female in the group asks if I want to see some sharks. I'm a little confused, but say okay.
There is a gentleman lying on a large beach chair thing with the straps that run crosswise up the length of it. He has nicely groomed white hair and an aquiline nose. Small creases near his eyes betray his age. He is reading a magazine or large book. One of the individuals looks to him for approval, and he indicates he doesn't mind if we splash around a bit.
I'm standing next to the concrete as one of the guys dives into this large pool area, then someone else swims out to join him. Soon the sharks come, attracted by the movement and noise. We are swimming with the sharks. It's kinda funny, because they are swimming upside down, their jaws open. One guy is laughing about it. They are easy to see and avoid. And then they guy who was laughing about it forgets, and a shark slowly moves up and engulphs his leg and bites down. The guy on the chair thing points out that you've got to be careful.
