This sounds a lot like me growing up and some still today. This may not work since you said that he incorporates everything into his dreams but does your son take medication? I ended up setting my alarm clock an hour before I had to get, woke just enough to take my meds and then went back to sleep. I had a second alarm clock set just in case but typically my meds would kick in about 15 minutes before the alarm would go off and I was able to get up easier. Good luck!
