I woke up in the middle of the night with these words in my head.. I felt like I'd just said them out loud almost. Or heard them said to me out loud. It was very strange, and I repeated it to myself several times in my head before going back to sleep (I didn't want to forget). I considered getting up to write them down, but I was at Elise and Jeff's and Meg and Elsa were right next to me, and I figured searching for my purse, and the notebook in it, would wake everyone up. So, I just went back to sleep. Now I'm not entirely sure this is the exact phrasing, but it is very close at the least:

When you lose what is closest to your heart, something else will grow in its place.
