Describe the startling objects that Pip finds in Miss Havisham's opposite room in Ch. 11. What does she intend to have happen there after her death?

This room is the famous room that Miss Havisham has kept
as a reminder of how horrible it was when she was "left at the altar."  The most
startling thing about it is how it contains the rotting remains of the feast that people
were supposed to enjoy after her wedding.  There are mice and spiders all over
everything, for example.  The wedding cake is beyond recognition -- Miss Havisham points
it out to Pip.

Miss Havisham also tells him that she
intends to be laid out in that room after she dies.
