I do believe there was a later episode where Garibaldi was handling a case of a "crazy person" {I think was it... DUST, no probably not?}, it's been a while. The man was having nightmares and a inferior officer made a comment about how crazy the guy was and something offensive or other. Garibaldi asked the inferior officer if he was drafted in the war and he replied, "I missed it."

Garibaldi goes on to saying that the crazy guy didn't miss it---inferior officer asks how he knew, and Garibaldi replies that he's had the same nightmares? So possibly? I think Garibaldi seemed to be involved? To what extent is never really known.

I could be completely off. But I distinctly remember this episode.
