Just my unimportant opinion, maybe he is like 1 brain 2 bodies hence he is mentally unstable in both of two dimensions. Maybe both were real world but his soul can't keep up as his mind is functioning at the same time so he can't help but move/ act the same way at the same time/dimensions and it just keeps clashing. Coz how can he imagine modernization? No one living in ancient time can imagine the modern technology. As for the things he brought to the modern time, well the situation is fantasy genre so that's not impossible I guess.
