Defying levity

Do you have a frequent nightmare that keeps in you on for years? For me, I named this frequent nightmare ” Defying levity” ( if you ever heard of the song defying gravity, it’s exactly the opposite of it. ) I’m always driven by the pulling force. It may happens in a lift. Sounds weird right. 

 So in a lift, as the lift goes up to a higher level, my body will levitate up as well until I hit the lift ceiling. No matter how hard I tried defying the levity, I still fail.
