Weird experience

I really don't remember my age when it happened. I think I was five or six years old when I experienced the weirdest incident in my life. I was dreaming that night. In my dream my older brother and I were arguing and fighting for a toy. He was grabbing my toy and I had no choice because he was stronger than me so I decided to throw away my toy so none of us would get it. After throwing my toy in my dream, I woke up. Everybody woke up. My parents said that they heard a sound of something falling from the second floor. We found out that the thing that fell from the second floor was actually the toy I threw away in my dream. The weird part was that my room was in the second floor. How did the toy fall down from the second floor. When I woke up, I was still lying on my bed and the door was closed.
