英语翻译Had i been dreaming,i would have dreamt of being someone

英语翻译
Had i been dreaming,i would have dreamt of being someone else,with a little creature burrowed in my body,clawing at the walls instead of my chest--a recurring nightmare.主要是不知道用什么时态来翻译,虚拟语气该怎么翻译也不是很懂,词的意思都懂,

如果我做过梦,梦里也一定是其他人,身体里有一只攀住墙壁的小生物,不是我的胸膛中反复的噩梦. Had I been… 是“If I had been…” 变过来的.是对过去的虚拟.翻译应注意时态
汉语喜人称主动 英语喜物称被动
