"God" is your superego, it watches you and punishes you based on your internalized morality
"You" are your ego, it is the idea of yourself that you have conjured up over time. The superego is an offshoot of the ego, meaning that as the ego develops, so does the superego. The superego puts restraints on the ego (through internalized morality and pinging your ego with guilt when you don't live up to the morality). The ego of a pagan and the ego of a christian can differ greatly. A pagan won't feel so much guilt as the christian. This is because their ego developed in a different environment. The environment that the christian gave more restraints to their ego.
What you really truly want and must fight to control is the id. The id is where your sexual desires, infantile emotional desires, etc. come from. Your ego thus regulates the urges of the id, using the rules of the superego.
TLDR: the feeling of being watched by the Father is really just your own superego watching your ego. The Father/superego has a a front-row seat to your thoughts, which is why you're inherently a sinner. The Father/superego knows when you covet your neighbours wife, and punishes you with guilt (ideally, in christian society) for it.
All this external metaphysical speak isn't really helpful.
