Except one has to be very careful about which dreams are animated, as this last-paragraph example from 'the Kuglemass Episode' by Woody Allen ably demonstrates:
Kugelmass, unaware of this catastrophe, had his own problems. He had not
been thrust into Portnoy's Complaint, or into any other novel, for that matter. He
had been projected into an old textbook, Remedial Spanish, and was running for his
life over a barren, rocky terrain as the word tener ("to have")-a large and hairy
irregular verb- raced after him on its spindly legs.
