But my blood surged with excitedment, as if I had already flown out of the room,straddled the neck of the North Wind and galloped off into space.請問老師gallop off into space應該怎么樣理解？

But my blood surged with excitedment, as if I had already flown out of the room,straddled the neck of the North Wind and galloped off into space.

剖析這個詞組的結構，看意思：

galloped （不及物動詞：飛奔）off （副詞小品詞：脫離房間甚至地球）into （介詞：進入）space（太空）

網友把上面剖析的詞義聯系起來，就了解具體的意思是了。
