dream

Last night I had this dream that it was a very hot day. So hot that almost everyone was staying inside, too hot to move from their beds. I hated lying around, so I decided to go for a walk. On the way I saw this guy that I barely knew, and he was wearing a long sleeved shirt. I thought that was very strange, so I decided to follow him to see where he was going. If it was cold enough to wear long sleeved shirts in this ridiculously hot weather, I wanted to be wherever he was going. Turns out, he was on his way to a muddy swamp, where hundreds of people were already jumping in and out, and as I looked closer, I saw that they weren't all human. Some were actually breathing while underwater!  i watched as people, dressed as if it were a cold fall day, stripped their clothes off to the bare minimum and jumped into the cool cool mud, caking their bodies and then they'd lie on the shore, on rocks and let the mud dry, and put their clothes back on.

What do you think this means???
