I never had nightmares during my 12 months with my stoma. During the first three weeks I was venturing out of the apartment for groceries just to have the movement, instead of having friends shop for me. I could do it, but it was tiring. I left the house without supplies, that was in the earliest phase before the stoma started to shrink so I hadn't experienced any leaks. Then I was off to a cure clinic for 3 weeks and the problems started, leaks all the time. When I got back, I took a little zippered bag that I got as a bonus from some luxury makeup thing I'd bought, and filled it with everything I could need for 2 bag changes: 2 bags, eakins, baggies, compreses, stoma powder, maniure scissors and a package of neutral ultra-senstive wipes. It went with me everywhere. The drag was that I could never enjoy just walking out with my keys in my pocket - I always had to have a shoulder bag with my supply case inside.
Then I got to the point where I could do a change anywhere, anytime (as long as there was a bathroom), in case of leakages, which did happen occasionally.
No traveling at that time so I didn't worry about what to pack in what bag. I did sometimes panic and check that the case was in the bag, that I hadn't left it on the table that morning.
What I wonder aobut now sometimes, is what if I'm in some kind of accident and am taken to the hospital, somewhere in the world, am unconscious and they exray me. They would see a jpouch and have no idea what it is, possibly think I'm a mutant species.
There were sometimes passing thoughts during those months, like being on a hijacked plane and being held hostage. But I stayed fairly close to home and probably won't plan major traveling until my jpouch calms down.
