meaning

Hi Teacher:

Could you please tell me the meaning of the bracketed sentence?

Just us who know can understand what it means. We have opened our eyes and have seen. [We're like people from way off yonder somewhere.]

Thanks a lot.

I'm not sure what this means in the context of the complete work, but it sounds like the writer is saying that they felt like people who were from a place so distant that they were nothing at alll like the other people around them.
