SAN FRANCISCOAlthough Jennie Wick, 23, cannot make sense of the dream she had Monday evening, its meaning is clear to everyone else, sources reported. 'I'm in this waiting room, and I'm screaming at this man dressed all in white who can't hear me,' said Wick, who is dating and financially supporting a University of California medical student. 'Then, we're at the vending machine, and every time I buy a candy bar, he grabs it. What's up with that?' Wick also failed to grasp what it meant when the man began to have sex with her best friend.
