Cover art for Hummer lyrics by Smashing Pumpkins, The

he is saying how religion and ignorance go hand in hand. if you're religious, you're ignorant to the wonders of life.

"Faith lies in The ways of sin I chased the charmed But I don't want them anymore"

sinning is something people naturally wanna do, but a lot of people don't because their "faith" is in the way of doing so. he chased the afterlife like all other religious folk, but he doesn't wanna be a part of the religious group anymore.

"But when I woke up from that sleep I was happier than I'd ever been" referring to being religious as being asleep - like being on autopilot in life, not really embracing and living it to the fullest. when he woke up from that long period of sleep, he was a happier person.

all in all, i think the song sends a message that says religious people take life for granted and don't enjoy it because they are too worried about being perfect in gods eyes just so they can go to heaven. and he used to be like that, but changed and experienced life in a whole new light.
