No, fatigue seems to play NO part in it. They occur the same whether it's after I have done a fairly hard days work clearing brush, etc. on my hunting property or if I have spent the day just relaxing. The dreams and the accompanying burning in my stomach can happen anywhere from say as little as 1/2 hour after I fall asleep up to say 2 hours after I fall asleep but I would say happens most commonly after being asleep about 1 & 1/2 hours and then repeats again and again until I finally wakeup / get up - stop sleeping. The dreams and burning happen ALMOST every sleeping period (happens even if the sleep might happen during daytime hours) without fail (7 days a week, 365 days per year), i.e. not just occasionally, this has been going on for about 20 years now back to when I was still working, have been retired about 5 years now, so, in my opinion, my stress should definitely should be on a lower level now. All of the dreams have NO relevance to the things I do and think about while I am awake. Many of the dreams are recurring but some are one-timers. The only way that I have managed to get thru all of this is by trying to get up as soon as I can force myself to and eat a small bowl of cereal and milk when I am woken up, which relieves the burning and may or may NOT allow me to go back to sleep for the next round depending how bad the burning from the previous session has hurt me. If I lay there and can't force myself to get up and eat the cereal, I have had it burn me so bad that the next day to three, my esophagus would be burned so bad that it felt like a mule had kicked me in the sternum. Not heart related, the doctors have checked many times.
