Feet in dreams and visions speak of the walk and the conduct of people. The condition of the feet reveals whether the specific person’s walk and conduct are positive (good) or negative (bad). Naked feet speak of a person who has no protection. It speaks of a person who is exposed to injuries and can get hurt quite easily (in a spiritual sense). No protection means that this person is not adhering to the word of God or the will of God pertaining to his actions. In a spiritual sense, it means he walks to places and in areas that he is not supposed to.
The fact that the feet were inverted in the dream speaks of a person who has things the wrong way round in his life. This person makes decisions and goes in directions that are often completely the wrong decisions or wrong directions to take. Such a person often does not know wrong from right.
The conversation that you heard is all about communication and/or counseling. Whenever people are involved in a conversation, words of deliverance, advice, information, wisdom, and even negative words that lead to destruction are used or can be used to influence each other. I think this person needs counseling so that he can start to walk the way God wants him to walk.
I think you pondered on a specific person and God showed you that things in that person’s life are not OK and he or she needs to be counseled. He or she needs to get their faith-walk in Christ or daily walk and actions in order according to the instructions of God.
The fact that you suddenly “woke up” just after the conversation, speak of the conversation opening your eyes (in a spiritual sense), and caused you to realize that the feet were naked and inverted. So the conversation is the key. This conversation brought spiritual insight.
If you can identify the trigger you will know exactly what this is all about.
