The whole Obito being able to come back in chakra form and go to Kakashi's consciousness isn't that far off reality in the NV.
Considering that
Minato and Kushina were somehow temporarily able to communicate with Naruto long after they died. So, the whole theory of Obito being able to return to Kakashi after he died isn't way off base.
You can also train your eyes to apparently do Izanagi long after you're dead and revive yourself. So what makes Obito any more BS than that?
Kakashi getting PS...now that was something...
