That is some story. I think your explanation is probably true, that your husband was in the same dream state and incorporated yours into his, you know how spouses sort of groove on the same track. Sometimes I think of something and call my husband and he is calliing me at the very same time with the very same thought.
I think I would have the same response, just not mention it ever. And odd thing happened like that to me concerning a strange dream involving my grandchildren and the very next day the details of the dream happened in real life. It still gives me chills and while everyone in the family knows about it, we don't talk much about it. But when I call my daughter with a dream I had, she yells to her husband "mom had a dream" and it is like one of those commercials where everyone stops to listen! They think I dream the future!!
God probably DOES engineer you dreaming about a future event, on occasion. How often is another question.
A dream journal could help answer that question.
