Swimming to Des Moines

A few days ago I had a dream where I was abroad a ship and wanted to go back home. I began to leave the group I was with an despite knowing that it would take bush-whacking over rough terrain and use of dead reckoning, I decided to go. Hiked through brush and over a crest and down the other side. I came to another (or the same) shoreline. Although, I had stumbled onto a docked luxury ship or some kind of well-to-do dock gathering that just wasn't part of my scene. I left, onto my journey and at some point realized I was headed to Des Moines, IA. I had to swim part of the way and in my dream's mind I visualized a map and it was of a Great Lake- the non-existent one that border Des Moines. I had traveled far and managed, somehow, to navigate the waters and land.
