一步三回头 meaning in Chinese

turn to look back repeatedly at every step

But after innumerable fluttering thoughts , like a man perfectly confus d and out of my self , i came home to my fortification , not feeling , as we say , the ground i went on , but terrify d to the last degree , looking behind me at every two or three steps , mistaking every bush and tree , and fancying every stump at a distance to be a man ; nor is it possible to describe how many various shapes affrighted imagination represented things to me in , how many wild ideas were found every moment in my fancy , and what strange unaccountable whimsies came into my thoughts by the way
这使我心烦意乱，像一个精神失常的人那样，头脑里尽是胡思乱想，后来就拔腿往自己的防御工事跑去，一路飞奔，脚不沾地。可是，我心里又惶恐至极，一步三回头，看看后面有没有人追上来，连远处的一丛小树，一枝枯树干，都会使我疑神疑鬼，以为是人。一路上，我是惊恐万状，头脑里出现各种各样的幻景，幻觉里又出现各种各样荒诞不经的想法以及无数离奇古怪的妄想，简直一言难荆我一跑到自己的城堡-以后我就这样称呼了-一下子就钻了进去，好像后面真的有人在追赶似的。
