peacefulmind,
You are a multi-dimensional being. "You" exist in zillions of planes of existence. The more familiar ones being physicality, the emotions, and the mind.
When you die, you remove your volition from the physical body. Everything else stays intact. So you still have your personality and all the other mind stuffs you had while living a physical life, because those are part of the mental body or mental dimension of self.
Now, if you're not familiar moving in other planes of consciousness, you will probably go unconscious after leaving your body because you'll have no clue what's going on. That's why we have spirit guides, to go fetch us when we're confused.
