It is a pleasure,
I just want to mention that I am myself sceptical to many prophets. This dream does not suggest that this particular prophet is always right. It merely suggests that a specific message or prophecy might be missed by you if you ignore him or her or a specific message that God wants you to hear and to respond to.
It is always important to test prophecies. The first thing is to make sure that it corresponds with the word of God. Also, we do not have to take or accept prophecies from false prophets. We are always led by the Holy Spirit and we regard the word of God as the most important aspect in our lives when it comes to doctrines and the will and the ways of God.
