Can't remember which class has the ability I want

[Drache64]

I am planning on moving my group back to Pathfinder after a year of 5e, before we migrated I was working on a necromancer character who could raise the dead and then possess his own dead corpses. It was a class ability or a spell, I can't remember where I found this, I thought maybe it was a witch but it doesn't seem like it.

Any ideas what this was or a better way to search?

Sorry I just googled "possess dead Pathfinder" randomly and found it was the Gravewalker witch
