I was dreaming I was an astronaut, along with a friend (though I can't remember who it was). We had made the atmosphere on the moon breathable. However, to be able to breathe it, I had to have my mouth right down on the surface, otherwise the air was too thin. My friend kept his helmet on so he could go around doing his experiments and what not. I kept my helmet off, despite the inconvenience of having to crawl everywhere, and despite developing some new moon disease from the plants that were responsible for maintaining the moon's new atmosphere. The only symptom I remember is that I was very tired. Apparently I have that disease, as I'm very tired, and I'm going back to bed for a little while.
