Yes, praying connects you to God -- doing so impacts your spirit. Subconscious is more of a secular term, unconscious a psychological one (terminology of the world). John 6:63 is a good verse to put into context Christianity's beliefs versus the world and its beliefs/terminology.
We are good with God because of Jesus. God also gives us over to Jesus and enables us with the Holy Spirit. The more you study God's Word, the more familiar you are with God, His will, etc. The more you pray, have fellowship with other believers, study scripture and theology, serve, the more you grow spiritually--it's a beautiful thing!
God bless you
