Why for the life of me I can’t stay awake when listening to Music?


I really don’t understand how someone can stay all night long listening to music? I read reviewers saying I started listening for hours till 2-3 in the morning. Well, I am 62 yo and as soon as I play music man I feel sleepy. I don’t think that is listening fatigue, it must be the opposite of it. I become so relaxed and my eyes start shutting down lol. Is that normal? Is it my equipments that makes me feel so relaxed or is it my advanced age? Can I do anything different to my system? 
I am not sure if this topic came up before and may sound silly but I thought I ask in case someone else on this forum has the same issue.

My system:

McIntosh c2700

Mcintosh Mc 452

Revivalvaudio Atlante 5

Garlubidor divinity dac

Eversolo T8

cables Audience throughout.

Thanks for sharing your experience and input in advance!

The same thing happens to me.  It really doen't matter on the music style.  Usually I dose off for a few songs.  I think it's because my mental mood changes and I release the stress and relax.  After a few songs I come back and then just continue my listening.  I don't mind because I feel really good after a quick cat nap.

+1 @hifidream recommendation to get tested for sleep apnea.  Getting a CPAP machine has been life changing.  I wish I had done it sooner.   I use a full mask as the nose pillow didn't work for me.

I still like to nap while listening to music.
