Hearing the Future

At the heart of much speculative fiction (and fiction in general) is a question. What if? On Tuesdays I like to throw one out there and see what you make of it. Do with it as you please. If a for-instance is not specified, feel free to interpret that instance as you wish. And if you find this becomes a novel-length answer, I'd appreciate a thank you in the acknowledgements. 😉

I'm back in my bedroom (yay!) after the deluge. It's not quite put all back together, though. There's still a big hole in my ceiling.

The contractors should come in about a week to replaster. Until then, there's a plastic tarp over the guts of my ceiling and the bottom of the upstairs' floor.

This means no insulation and no muting of the sounds coming from the bathroom above me. Which is what inspired today's question...

What if suddenly and inexplicably you could hear everything coming from one room in your neighbor's house from tomorrow? 

(I'm specifying a day in the question, but feel free to change the timing. The point is: what you're overhearing is not happening right now. Because I rewrote this question using tomorrow, yesterday, three years ago, and two years in the future, and I couldn't decide which timing was better.)
