Confusing Things

Something that I think is super confusing is Lady Gaga's new song "Judas". First she talks about it like it's a sin, then she starts talking about all this other confusing stuff and acting like he's a person. For example, in one part she goes "I'll wash his feet with my hair if he needs, forgive him when his tongue lies through his brain". What does that even mean? There's also a part when she says "I learned that love is like a brick, you can build a house or sink a dead body". That doesn't have anything to do with love; or a brick! Oh Gaga, how you baffel us all.
