I had a Lucid Dream by having a dream within a dream

I had a lucid dream by having a dream within a dream. So what happened was, I was in a random dream and then some boxes fell on me which made me "wake up" but as soon as I woke up I immediately knew I was still dreaming and the thing in the dream I was in a place that looked just like my room with the only exeptions being that there was a laptop on my bed and my plusies were different. During the dream there was random stuff happening outside of my door and the only thing I could control was making the random cat outside my door dissapear. This was the first time I ever had a lucid dream.
