using "natte'ta" in a sentence


in this sentence "natte'ta" is used:

"tsumetai ame zubunure ni natte'ta watashi ni"

i don't understand how the word "natte'ta" is used or its meaning. How would
the word be translated to english and what tense is it in?

i'm really confused about the word




なってた is the casual abbreviated form of なっていた ([see this
chart](https://japanese.stackexchange.com/a/18159/5010)). なっていた is the te-form
of なる followed by the past form of the subsidiary verb いる for denoting
progressive/continuous aspect. なる is [this
なる](http://jisho.org/word/%E6%88%90%E3%82%8B), and here it just means "to be".
So 私はずぶ濡れになってた literally means "I was being soaked with rain."
