stumbling across

To my patient's surprise, simply stumbling across the idea that he could comfort himself seemed to grant him the power to do it.

让我的病人吃惊的是，只是跌跌撞撞地经过“他可以安慰自己”这个观点似乎赋予了他这样做的权利。

All who had got their meals covered the bowls with straw hat or arms while stumbling across the muddy courtyard to the dormitories.

所有打了饭菜的人，都用草帽或胳膊肘护着碗，趔趔趄趄穿过烂泥塘般的院坝，跑回自己的宿舍去了。

This, in fact, is the idea my patient found himself stumbling across.

事实上，这一点正是我的病人发现自己正跌跌撞撞地经过的地方。
