Door in the Floor

This video is short and powerful. The person who shared it with me called it, "The door in the floor", which of course I had to look into. Doors have been an integral part of my healing recently. I swear I saw that title somewhere when I first went to see the video, as well, but now I can't find any word around it except "forgiveness". So, if you can clear that up for me, I would appreciate it!

I suppose there are a multitude of possible doors, and my goal is to open them all.
