Okay, I couldn't sleep because of this

At the end of the session, my T walks from the room we were using towards a hallway. In that hallway there is a couch against one of the walls. As I was walking behind my T, I looked down the floor. Between the wall and the couch I saw a small squared package. Ok, that looks like a condom, I thought. Although I didn't recognize the brand. I went to bed and the memory popped up in my head. I just don't know what to think of it. I was somewhat tired. Could it be that it was some of those little bags that absorbs the room's odor?
I can't wait to the next week and somehow make an excuse to look behind the couch
