这句话还是定语从句吧?

这句话还是定语从句吧?
I saw a sight that I wish I hadn't seen

如果没有 I wish的话 :I saw a sight that I hadn't seen,that引导了一个定语从句,并且代替先行词,a sight 做seen 的宾语.

那:
I saw a sight that I wish I hadn't seen

( I wish I hadn't seen,还是属于定语从句吗?)
I wish 后面的部分 I hadn't seen , 属于 wish 的宾语从句了,那整体还是属于定语从句么? 谢谢啊.

我如果这么写I saw a sight that I don't / didn't want to see可以么,语法是否正确?
don't 是不是要用 didn't

谢谢
