I had a hard time trying to get difficult child 3 to tell me his bad dreams. He didn't want to, for two reasons:
1) Dreams evaporate, leaving just the bad feeling (which is why I would try to get him to tell me right away)
2) He said he didn't want to upset me, but I think he found the re-telling upsetting.
I still made him tell me, it helped me get a better understanding of what was likely to be bothering him.
I told him that there are two good ways to make a bad dream go away. The first one is to tell it; the second one is to roll over in bed so the bad dream trickles out of the ear that WAS up and is now down.
(Telling the dream - it takes time, awake, which turns off the dream sequence so hopefully that dream is now gone. And rolling over - similar, it changes the body's position often enough to change the sensory stimuli that are am important facet of THAT dream).
difficult child 3's days were so stressful for him that his dreams were often upsetting and stressful too. Dreaming is what happens as you process your day - when the day is particularly complex to process, the dreams can be jumbled, confused, vivid and upsetting.
With food - I used to keep food like cooked sausages, fruit etc available to be raided. The kids would come home from school and help themselves. difficult child 3 helps himself to bread (which I keep in the freezer). He eats it frozen, with nothing on it. He then leaves t he empty packet in the freezer. Empty packets everywhere, even though I keep calling him back to go tidy up.
Screaming point, sometimes.
