I don't remember exactly where I was when I became lucid and I don't know why. I was in a house and I did math in my head to become more lucid. I walked through the house and went outside. It was a big open space with hills and houses here and there. And it was by a huge lake. I came to a cliff by the water and flew off of it and over the water. Then I was in a bedroom with a bunk bed. It was like an apartment with lots of people from church in it. I realized I was still dreaming, so I got out of that room and I ended up in a huge hotel. I went to different floors and explored the different rooms. Sometimes I'd bump into people I knew, but nothing terribly interesting happened. The rooms were fancy though. A few times I felt like I was waking up, but I focused on the dream and stayed in it.
