During a marathon OR session, everyone grabs quick naps and has disturbing dreams. Ensemble nirvana. They aimed big with this one and found iconic touches, and images so subtly disturbing that they might filter into the viewer's dreams...Margaret in a bloody wedding dress, BJ dancing with his wife Peg (the first of two memorable appearances by Catherine Bergstrom), Winchester performing cheap parlor tricks trying to save a life, Hawkeye losing two arms to an unforgiving professor, Klinger in Toledo watching himself on an army operating table...not worthy of a top-ten list, but one hell of an effort. Also...maybe she just had an off-day, but on one of the few occasions they gave Nurse Kellye (uber-supporting actor Kellye Nakahara, the only non-regular to appear on the M*A*S*H IMDb title page, with 166 episodes, 11 more than Radar) an actual scene, she comes up with a, shall we say, unfortunate performance.
