How about the classic mind-bender, THE CABINET OF DR. CALIGARI, with its deliberate confusion between real/imagined/insane? Also, John Carpenter made one of these, but the name escapes me. It is interesting to think about the history of this representation. As Donald Larsson points out, film has been used since its inception to toy with notions of the 'real.' SHERLOCK, JR., anyone?
