Spiritual Awakening is awakening from the dream of thought.
Since ancient times the term awakening has been used as a kind of metaphor that points to the transformation of human consciousness. There are parables in the New Testament that speak of the importance of being awake, of not falling back to sleep.
The secret of awakening is to unconditionally accept this moment as it is.
For a relationship to deepen, at some point the spiritual dimension needs to come in. You don't even need to be fully awakened for this to happen, but if it does happen it certainly means you are awakening.
