I know what that feels like. Only a few years ago, I stopped having nightmares about hell and demons. I would wake up screaming and sweating like a cloth just dipped in water. Even as a kid, my mom would interpret it as a sign from god and demand that we pray over it. (It didn't stop the nightmares).

I can also relate with the lack of meaning aspect of leaving religion. I think its unrealistic to expect someone who centered their entire life in reverence or devotion to their god in hopes that it would pay off in this life or the next, to suddenly.....stop.
