What is going on?

Recently I've been waking up from my slumber every morning to myself singing. It's not the singing that throws me off...but every morning as soon as I wake up I find myself singing praise songs. No, not humming, actually singing the words. I can't even remember half the words to praise songs nor do I listen to them outside of Sunday. But somehow, some way, I wake up singing songs of praise. WADAFA? Brain Explowned.
