Take whatever I say with a grain of salt, but I feel intentions(not to be confused with intentionality) help a lot here. They play a distinctive role in the etiology of attention(and the subsequent process of resilience building), one of the fundamental aspect of dealing with psychological issues. For eg, Whenever you become aware of these nightmares, try to observe the casual chain, eventually your mind will be inured to these episodes and will become much better at threat detection. Something like a mindfulness(Vipassana) retreat can help with this a lot.

My experience has been that most of the psychological issues can be resolved to a great extent by employing the "redundancy of potential command a.k.a Self-Organization"(See McCulloch). Meditation does this by asking you to bring back the wandering mind again and again. But you can also do this voluntarily by repeatedly observing the stress inducing conditions such as nightmare(in your case), which can help your brain better adjust and detect patterns.

This makes more sense for someone who might suffer general anxiety or "work stress" or relationships stress.

In my case, we're facing a crisis - so we know the source, and that it's temporary (one way or another).

What do you mean by we know the source? At best, you can track the functional(mri) and structural(pet) aspects your brain if you take the neuroscience route, and the behavioural(cbt) aspect when you take the route of psychology. It seems to me that the unique experience i.e., the unwelt is out of reach without some form of mindful confrontation/adaptation.
