Also, in Greek mythology, there's this lady named Cassandra who can see the future, but one of the Greek gods cursed her so that no one would believe her predictions. Professor Trelawney's grandmother's name is Cassandra. BOOM!
Oh my goodness! I'm rereading Harry Potter for the third time, and I was wondering if anyone else just realized; in the third book (I LOVE PoA!!!!) its Christmas time so everyone is sitting at the same table for dinner. Dumbledore gets up to seat Trelawney, but she freaks out, saying "When thirteen dine together, the first to rise is the first to die." Except... Scabbers was in Ron's pocket. Scabbers, otherwise known as Peter Pettigrew. So there were already thirteen people at the table. And Dumbledore got up. Mind BLOWN!!!!!!!!!!!!!!
