Personally I subscribe to the big bong hit theory myself
. To me, it's all about escape and Heaven's a place where you're not supposed to feel pain and all is good...same as while you're high or drunk. When reality hits, sunrise, you're coming down off the high, and you long once again to get it back. Like dreams, it's all temporary, fleeting, and not real. I don't know. That's my two cents.
