The power of God speaking through dreams Is this ...

Generally speaking, dreams are thoughts/desires/fears that our subconscious tries to communicate to us.

On the other hand, you'll find less dreams in the New Testament than in the Old Testament. And I strongly believe that after the completion of the Scriptures, God no longer communicates to His church through dreams as much as before. He would be speaking through dreams more to non-Christians (those of other religions) since they don't have the light of the truth- the Bible.

You're talking about marriage... such a sensitive issue. If the dreams are the only sign, my personal opinion, don't go with them, for 2 reasons: 1- you don't initiate such a serious relationship on the dream basis. If God wants to tell you His will, He would say it in other ways as well. 2- if this is God's will, He can't be telling it to you alone, since you're gonna marry "another".

In most of our decisions, God simply speaks through who we are. I mean... He formed you in a certain shape and He surely wants you to marry someone with whom you have harmony. I don't know about "Joseph", but if he is so different than you (character-wise I mean), then it can never be God's will for you to be together.

Think & pray about it. God will make you understand if you are truly faithful in knowing and doing His will.

God bless

God isn't fussed that you follow his will to the letter but that whatever you do with your free will doesn't blatantly contradict his advice on the matter. A little variation of his will is permitted.
