When you watch it, there is a scene in which DeCaprio goes into the bathroom after waking up from a particular disturbing dream.  He takes his spinning top out, and spins it on the sink, however, before it falls, the asian guy walks in and he knocks it off of the sink, never knowing if it falls on its own or keeps spinning.  and that asian guy saw his totem.  THE WHOLE MOVIE IS A LIE
