Generally I find songmeanings.net to be a good source for interpretations. This one caught my eye:
"The band themselves said it's based on "Where The Wild Things Are." It's about loving someone so much you'd be willing to hurt yourself or hurt them to keep them forever. It's specifically based on the line, "Please don't go. We love you so. We'll eat you whole."
All of this stuff about drugs and cannibalism is stupid. The band wrote an abstract song about an abstract topic. Obsessive love, folks, that's all it is."
