What does it mean when your going up in an elevator with an old friend & its going uncontrollably upwards fast?

I was in a elevator/lift and it started going to the top floor really fast out of control fast and me and my friend where getting scared because it was out of control and the roof started getting smaller in the lift but then it started to go fine we came out and looked out the window and saw an ocean large ocean but it was like a computerised ocean and some of the ocean turned into a giant sea human but you could only see the back of the body with the face just turning around on the shoulder, then the water body turned back into sea.
