I was at a party and had to go to the bathroom. I went into a smallish, somewhat dark home bathroom, closing and locking the door behind me. For a moment, I almost panicked, realizing, not exactly that I was dreaming, but at least that I was having a bathroom dream, which often turn for the worse when the bathrooms are haunted or filthy or there's no decent toilet to use. But then I realized that I had been able to lock the door. This would keep out any unpleasantness!
The toilet in this little bathroom looked a bit dirty, but there was another, large, brightly lit room just off of it, so I flushed that toilet, and moved into the next room. It was a big, white-tiled room, with a strange, but fine toilet in the middle of it. I looked around the room briefly, seeing at the far end of it, my husband standing, looking back at me. He disappeared then, and the bathroom was all mine. I jump-flew around a bit, used the toilet, and woke up. It was invigorating.
[This was just the very end of a much longer dream, but this is all I could really recall upon waking.]
