Embarking on the Alpine Trail: A Journey to the Vast Cavern

This is a recount of my dream last night.

I was hiking up an alpine trail, as I got to a log crossing the path, Ben Greenfield (yep) grabbed a speed boat, and we started hauling it up the trail. All of a sudden, we are in a vast cavern/beach area. The waves hitting the shore are massive. It's not only us now, but there is an entire group, and I get the feeling Ben is teaching us something. He jumps in the boat and shows us how to ride the massive waves into the shoreline. On the shore we can see there are openings in the cavern wall where we can see outside, and it looks to be a city or shops where people are passing by, eating and drinking and some are watching us. We don't ride in the boat, but instead, we are now on the opposite shore of the cavern walls I just talked about, and then the water goes completely flat. Ben, myself and a woman start to make our way across the water. Ben asks me my name and then we start swimming, as we reach the shoreline I can see the people outside of these glass-covered cavern walls and for the most part they pay little attention to us.
