In Matthew ch 2, there are 4 dreams that take place.
In each, the Lord uses them to instruct people to go or not go places.
1st : " And having been warned in a dream not to go back to Herod, they returned to their country by another route. (v.12)
2nd : "When they had gone, an angel of the Lord appeared to Joseph in a dream, 'Get up', he said take the child and his mother and escape to Egypt. Stay there until I tell you, for Herod is going to search for the child to kill Him.'" (v.13)
3rd: "After Herod died, an angel of the Lord appeared in a dream to Joseph in Egypt and said Get up and take the child and His mother and go to the land of Israel, for those who were trying to take the child's life are dead." (v.19)
4th : "Having been warned in a dream, he withdrew to the district of Galilee, and he went and lived in a town called Nazareth." (v.22)
I love how God talks to Joseph in the dreams and not Mary.
Mary has been blessed among women to carry Jesus.
But God is directing and guiding Joseph, allowing him to be head of the family.
And about dreams, I know we all have bizarre dreams and not everyone has a significant meaning.
But I also have blessed to be warned about things in my dreams.
Will I fight a doctrinal war over this? No.
But I have had dreams , I pray over them for God to reveal the meaning to me..
And sometimes, not nearly enough :) , I get answers and they have helped me.
