Authority, Keys, Houses, School, Questions and Babies?

Authority (Pastor and wife, teacher)
Houses (Pastor's house and new house)
Keys (to classroom and car)
Baby
Questions (to Pastor and from Pastor and to teacher)

I had all these symbols in 3 dreams a few days apart do you know what they symbolize?

Well, God's government could be represented here. Jesus the Head, Pastor under the authority of Christ, his wife in submission to her husband and as Pastor and the teacher under the submission of God, Pastor, and Wife. Check out these scriptures: 1Cor. 12:27~31 and Ephesians 4:11~16
Houses sometimes represent the person or you. This is what Mia's has for house symbols: http://www.heartsongministry.com/dream_symbol_h.html
Keys may be keys to the kingdom and if it were to a classroom this may mean that you are going to teach anointed by God, the car may mean ministry, and sometimes even a traveling ministry. Who is driving the car? (Leading)
Baby can represent new birth or depending of the age of the baby how long something has been going on.
Questions may be what is in that persons heart. Maybe these are questions that person has been asking God or praying about.

Just some thoughts!!!

Its not good to take things out of context, as the symbols are written you would be given the position as a pastor.
But that is only symbolism, You have to keep these in the perspective of the dream.
Maybe the results are the same, maybe there not.
