Once the bugs are on their way gone that stops the adrenal stimulation. That's when the deficiencies show up. The effects of the stress show up after the stress. See that a lot with nasty divorces and high stress life problems. Don't fall apart till afterwards. Same-same nutritional deficiencies.
Nightmares ARE B1 deficiency. High stress burns up B1. B1 is water soluble. B2 is fat soluble. B1 burns up quicker than B2. Easier to get too. Eat your spinach or get some Cat B.
Been through it many times this lifetime. Try it, you'll be surprised. No more nightmares.
