mount the clouds and ride the mist—speed across the sky; feel dizzy (/giddy) 〔as if in a mist〕/道静头脑昏昏沉沉，好象在～。(杨沫《青春之歌》37) Daojing’s head was heavy and she was too dizzy to think coherently；…/原来是～的神圣下界！ 怪道火不能伤！ (《西游记》226) So you are actually an incarnate deity who knows how to ride the fog and sail with the clouds! No wonder fire cannot harm you!
