I think this is a question you'll need to largely explore yourself.
For one, as with anything here - if you are hearing voices, you should make sure first and foremost that your mental health is on par. It's always good to rule out the mundane before moving on to more divine assumptions. However, assuming all is good on that front, this sounds similar to a type of horsing/possession in my practice that we call shadowing. You can read up more on that here:
As for the specific path or deity, again - I think this is something you'll need to seek more details into yourself. Many deities are known as "one with many faces". Loki for instance, in my practice, is seen as a multi-faced deity and has many different kennings to describe him. It'd be best for you to try and prod for more detail, in my opinion.
