I have the same question I always have about things like this. If God wanted to send you a message, what reason would he have for being so vague? So absolutely ambiguous. If he's omnipotent and has information for you, surely a loud noise is not an effective way to share it.

Other ineffective ways to send important messages include: floods, diseases, unexplained substances appearing on religious statues, images on toast, etc.

Practice rejecting the belief that all of your time must be productive and that rest is not the right thing to do even when you're sick. (In all seriousness, you might try mindful, intentional rest and notice the thoughts and urges that come up in resistance to that. Question them all and reject the ones that don't enhance your life.)
