You said it yourself. The significance only you can know. As I read your post I looked up at an unfamiliar bookshelf and saw a title "Fly Like a Butterfly".
After my surgery I had a most persistent spider who crawled in circles on the wall in front of my face until I got the point. The point was only for me to know and determine. If I think about it too much I might doubt myself, or the message. I just simply KNOW. It's enough for me.
