Dream #227

ok i had this dream a while ago. i was on an elevator with my parents my sister and her husband. the elevator had no walls on it and we were really high up. when all a sudden i almost fell off. But my brother-in-law grabbed my shirt and stopped me. Then he said you want to see something really cool. before i could answer he grabbed my shirt again and he jumped off the elevator and pulled me with him. We were free falling and i could feel the wind and everything. I even felt my stomach move(like when on a roller coaster) and we were less than a foot from the ground when i woke up. After i woke up i was sweating and my stomach still had the dropping feeling in it. I have only had this dream once(that I remember) and never actually hit the ground. I want to know why my brother-in-law who i have known since i was 4 did this to me.
