Jump On It!

In a recent dream, I was in a backyard that was covered in luscious, green grass. As I was walking around, I came upon a certain section of the yard that was extra bouncy. I soon discovered that I was walking on a trampoline. I've seen plenty of ground level trampolines, but I've never seen one that is covered in grass. Now my roommate thinks that I should market the idea. She is often heard saying, "You should market that." I have no idea if such a thing would even be possible to make, but if someone figures it out, I would totally buy into it.
