How could I forget something so crucial?! I guess that’s what exhaustion does for a person.
Instead of rewording what I’ve already said in a comment I wrote from my post Sleeping With Insomnia, I’ll just copy and paste it here. I think the information is too vital to risk the chance that others may miss benefitting from it.
I see what I’ve neglected to add and am reminded of things I forgot about my childhood. My parents always had me go to bed in my own bedroom, but in spite of that, I didn’t end up staying there for the same reasons as your son’s. After having written this post, I asked how many other adults in my aspie group have to deal with nightmares. Surprisingly the answer was only a few do. This sleep disturbance seems to be more prominent among children. I think there are too many factors which could possibly be acting upon the way one sleeps as an adult for any ‘professional’ to be able to give a reliable answer.
I may have given the wrong impression, since I too get overstimulated by anything electronic. Having said that, it probably makes little sense as to why I sometimes use a CD player for help to sleep. On the nights I listen to my CD, my mind tends to be extraordinarily overstimulated all on its own. I have no idea what percentage of the time it works. All I know is that it has given me a break from my own inability to ‘ground’ my thoughts. It takes discernment and practice to know what things can be focused on without over-focusing on it (you probably already know that).
I heard the advice of eastern meditation (e.g., focusing on breathing to stay in the ‘present’). That doesn’t work for many aspies. A tip I failed to mention has a perfect success rate for me. I forgot to include it, because it had been a long while since I last experienced it before writing this post. I can remember to include it in this comment due to finally getting this ‘treatment’ last night. My parents would never have done it for me, but fortunately I must have intuitively known to give top priority to marry a man who is gifted with knowing how to give a massage. My husband never was taught any techniques. He just knows how to squeeze the anxiety out of me (he should, because for many years, he was the greatest contributor of stress in my life¹ and I thank God that’s over!). It isn’t often I get to receive his therapeutic strength, but when I do, it works 100% of the time!
I did have the same Alexandar Scourby’s CDs as yours, but gave them away because of the way he talks (like there is a fire in his mouth and the words are running out to escape for their lives!). It’s critical that I listen to a soothing voice speaking at a slower pace.
I finally got a needed wonderful night’s sleep what I last night! 
¹He admits it and now sees what he couldn’t back then. Only the ignorant would claim this is an arrogant statement.
