Hawk's Nightmare (5x13)

:

After Hawkeye bemoans the young age of the wounded, he appears to develop problems. Sleepwalking and bad dreams, according to Sidney Freedman, are taking Hawkeye back to a simple time, but the horrors of war continue to intrude. After Sidney's assurances that he is as sane as can be, Hawkeye's life once again seems to settle down.
