I agree with this because I never wake up in the night with any thoughts of gods or anything connected with them, and this includes ideals of hell.

I worried about "Hell" when I was young, being raised in the bible belt that was preached to me every week. After I realized it was all crap, I sleep very good now that the magician in the sky isnt waiting to throw me in a pit of fire....LOL

Me wonders if they are better snores too?

Clearly an average; I'm a horrible insomniac.

A sleep study would probably show that I'm best adapted to a 30 hour cycle, awake for 20, sleep for 10. Too bad I haven't found any way to do that and still make money.

I guess it has something to do with the lack of guilt only. But if you have other problems for sleeping like insomnia, depression, bipolarity, stress, ADHD, that won't go with atheism or agnosticism.
I personally sleep better after exhausting exercise or work, or a good whiskey at night!

I was raised catholic, had nightmares of being in hell when I was a child. These days I sleep pretty well, but I take sleeping meds.

When we go to sleep, we may never wake up. They may wake up in hell. LOL

I have some weird phucked up dreams that can wake me up in the middle of the night. I'm an atheist.

Hey. Baylor University is a "private Baptist research university" (per Wikipedia) in Texas. I'm sure they consider themselves very serious. Lol.

No sin guilt

What a lot of old twaddle!

I've been an insomniac all my life, theist or not, however I no longer have nightmares about old nick, there is just too much real nightmare fuel out there to worry about now.

I don't know about this. I've been an Atheist all my life, not avowed but I never believed. I had sleep problems my how life. Since I've gotten older, my sleep patterns are good.
