These visions can mean many different things to different people...however, only God can reveal to you what the significance of these are for you.
Don't forget, these visions may already be God's answer...not all of God's messages to us come like a lightining bolt from the sky, many times they are very subtle; it is up to us to make meaning of what His message for us is.
I ask that you give some clairity to this person regarding the visions that have been presented to them. If this is a message that needs answering (spiritually), please work within this person so that they may understand the direction they are to take.
Lord, we know that you will never lead us in the wrong direction, but we are falliable and stumble, please walk with this person and direct them to the path that you are pointing through these visions.
Good luck and God Bless.
