rope swinging

Date: 6/25/2016

Can't remember whole dream: I remember rope swinging like spider man but without the web's ( it was metal chain) I was rope swinging inside a very open but dark and foggy metal tunnel. below me was very misty but some tall metal containers were visible riding out of the depths. then after swinging for about five minutes I swung and landed on this raised platform / bridge which had metal barriers on it and a metal grid floor. thats all I remember.
