Could you explain how does the 俺が作り上げたのではないことは and the でもない work here?


> 俺が作り上げたのではないことは、昨日の行動からして自分が夢遊病だったり第二人格でもないと無理なのは解っている。

Could you explain how does the 俺が作り上げたのではないことは and the でもない work here.

I guess it's "I fact that I didn't make it up"

As for the でもない I guess it's like

Judging from my conduct yesterday it's neither due to sleepwalking nor a
second personality.

Can someone correct me on this?




This sentence is certainly confusing, but I would parse this as a sentence
with two long topics marked with the two は. This sentence can be safely
divided into two sentences:

>   * 【俺が作り上げたのではないこと】は解っている。  
>  I know that it was not something made by me.
>   * 【（昨日の行動からして）（自分が夢遊病だったり第二人格でもないと）無理なの】は解っている。  
>  Judging from what I did yesterday, I know that it (=making it) was
> impossible, unless I were a noctambulist or had a second personality.
>

>
> The topic (noun phrase) is marked with 【】)
