Yes, the kokugos split.

Shinmeikai puts it succinctly:

(一) 死者の魂。
(二) 幽霊。

I don't agree on lumping these all together. The kokugos 
split into two senses, the first of a dead person's soul, and 
then a ghost. Culturally, there's certainly a difference 
between the two:—with a soul being the spiritual essence 
of the material body having become unbound, and a ghost 
the manifestation of the dead. I personally view the former 
as religious and the latter as folk belief, though of course 
in actual usage the distinction might be muddled.
