"I shudder to consider eating a full bun or something but I haven't tried in years."

I have it nowhere near as bad as you (which is why it went undiagnosed until I was 30... although it's still pretty bad). But for about 5 years after I found out I would have recurring dreams where I would be eating a hamburger and realize after swallowing "Oh, crap, that's a normal bun!" I suppose in some sense that might qualify as a nightmare the first couple of times, because it would fully wake me up.

I also have Celiac disease, somewhat less severe than nibstwo, and I also have recurring dreams where I eat something (usually pizza) and midway through realize it is made with wheat dough. This was further compounded when once I ate a package of vegetarian chicken wings (made of wheat gluten) which was mislabeled at the grocery store (gluten free tag on the price label) and next to veggie burgers by the same brand with the same packaging where ARE gluten free and I had eaten before without a problem... I was sick for about a week, couldn't work or think straight. I won't make that mistake twice!

Another funny angle--I also have Type 1 diabetes (diagnosed when I was 9) and for a long time after diagnosis I had dreams about drinking a 64oz soda only to realize it wasn't diet, and panicking since I would probably be in DKA soon after!

Maybe there is some immune system disease/nightmare link that has gone undiscovered :)
