interpret THIS

Dreamed that I was making grilled-cheese sandwiches, only they weren't sandwiches, they were paperback books. I was cooking up paperback books in a frying pan. Butter on both sides, medium heat, flipping them over ... watching for whether the covers were getting nice and golden brown.

Oh oops! I tried to grill a hardback! So frustrated with myself: the crust will be much too tough and the heat will probably not penetrate to the center. Maybe I can cut off the spine at least....

The dream didn't get to the eating part.

They weren't books I was interested in reading. I don't recall the titles.
