Explanation:
He tells us that he has had a dream -- a very unpleasant one. He has dreamt that he has changed from from a person (he had a name) to something that was large and ugly. His bed covers did not cover him and it allowed him to see his distended belly which was rib like and confining. His back was armor like; it was not flexible which added to his discomfort.
Worst of all were his legs which were like connected pins.
This is the introduction to a very dark tale. If you think it is optimistic, I'd hate to read anything you thought was pessimistic.
