Pebbles and Dragons

Date: 5/22/2019

So in this dream i dreamt i lived in a world of dragons. And humans were all born on this island made of smooth round pebbles. And the relationship between these dragons and these humans was that you had to fill a round, softball-sized glass bottle with these pebbles and then seal it with a cylindrical stone in order to be able to become greater friends with a dragon and be able to ride it and harness its power. So i did just that and then my dream shifted, as if to put me on a mission to further find pebbles. I was at my high school (my high school is a common recurring thing in my dreams). At the high school, it was clear it was the end of the day because of the sunset going through the windows and the smaller number of people going around. I was traveling from corridor to corridor in order to find the stones to fill my glass bottle i had in my pocket from my last phase of my dream. After a while my dream shifted again and I was on the shore looking for pebbles again with the other humans. Nobody knows where we got the glass bottles.
