Astrocamper

I'm lying in my sleeping bag, 

Which lies in my tent, 

Which lies inside a valley, 

By a river that is bent. 

Above me is the tent's roof, 

Above that are the stars,

And asteroids, and satellites, 

And planets such as Mars...

Below me is the tent's floor, 

Below that is the ground, 

Consisting of our planet, 

Which is big and hard and round.

I feel as though I'm anchored to, 

A firm and solid base,

It's hard to comprehend, in fact, 

I'm spinning fast through space!
