I decided to take a walk downtown near where I live from my apartment. As I was walking I saw an animal on top of a truck. From afar I wasn't sure what it was. For a moment I thought maybe it was a deer that someone had shot or hit and killed and had then tied it to the top of their vehicle (it wouldn't be the first time I've seen that). As I got closer I realized it was a dog sleeping on top of the cab of a large pickup truck. It fit well with my daily prospective memory training as one of my four targets was to do an RC the next time I see a dog! It did make me pause for a moment and wonder a little more meaningfully whether or not I was dreaming.

That's awesome that this thread has helped you with your lucids already! The floating and expansive feeling sound really neat.
