How do ancient ghosts write?

Oracle Bone Inscriptions's "ghost" glyph has a "person" below it and a terrible head (not a "field") above it, which is a monster in people's imagination. That terrible head in Oracle Bone Inscriptions is probably a mask! Ghosts, people belong to ghosts. -"Shuowen" because the word "ghost" means the human soul, and the soul itself is a more abstract thing! And it is hieroglyphics! Therefore, it is a concrete thing! In that era when totem worship was prevalent, after death, there were bound to be some ceremonies, and the word "ghost" was probably born at the earliest ceremony.
