A friend from school had an apartment on top of a tower crane which came out of an apartment building. There was an elevator going up but you couldn't go inside but had to cling to it on the outside. The elevator's motor was inside the apartment building and I felt sorry for whoever had to live there with the noise day and night.
Well, I'm not too good with heights so clinging to an elevator while going up dozens of stories wasn't pleasant. I realized I just had to hold on and not let go but at some point I realized this made absolutely no sense and became lucid. Only to wake up.
