Was on a business conference call until 4:30. Then headed to the shower. Before turning on the water I heard another word pronounced aloud but could not identify what the word was. Might not have been English; maybe that's why I didn't recognize it. I did hear what sounded like two footsteps on our wood floors while I was in the shower. Our floors don't creak. And, my dogs didn't come upstairs because I put a gate up to prevent it before I got into the shower. After existing the shower, I heard what sounded like very soft music - very melodic. Nothing that I would expect to be played by a neighbor or a passing car at a volume loud enough for me to hear inside my house. Wasn't the TV downstairs either because my DVR has a timer on it which shuts it off after an extended period of inactivity - I checked and the TV was off before I got into the shower.
