What you showed was an example of thinking by association one idea triggering the next. All this is based on previous experience, the past which is dead. This will lead if followed with precision, to the realization that thought is a prison. When one experiences the utter hopelessness of this kind of thinking to solving the emptiness of the heart, one can come to the end of thought. There the mind can turn inside out and God appear. God, knowledge, realization, love, being, certainty, whatever word you want to use, it doesn't matter. You are not alone. You have a friend in the dark whom you don't see because he looks out of the same eyes that you do. You are not alone. Do not think about it. You are not alone.
