There is a difference then between prayer and prophecy. Prayer is a priestly activity; prophecy is obviously a prophetic function. When we pray, we get the vision, when we prophecy, we deliver the vision or communicate it (it involves communion with God AND humanity). I often see things in prayer, but when i come to prophecy them, i have to translate what I saw into a language which can go “into” that person or situation. So there is something of interpretation in the role of the prophet.
