dream fragment

This happened over a week ago, but I'm recording it here now.

I remember very little, but I remember several fragments of different dreams. The first dream repeated twice, and I know because after the second time, I knew what somebody was going to say before they said it-- I'd heard it before. I realized that I'd seen all of this happen before. I was sitting in a hotel room, I stood up and shouted, "I'm lucid dreaming!", and the the dream faded to black. I "woke up" in a similar hotel room with my brother sitting across the room. I told him, "I just lucid dreamed!!", then that faded to another dream. It was strange, because I remember thinking back to and recalling my few seconds of lucidity, while I was in the next dream. I don't remember the dream, but that while it happened, I kept thinking back, like, "wow, I finally LD'd!". That is all.

This morning I fell asleep after my alarm went off. When I woke up, I scribbled down "cat", and "the secret lies with Charlotte". I was very sure of what I was doing. I now have no clue what I was talking about. National Treasure reference?
