Was Joseph's dream fulfilled or unfulfilled ?

Unfulfilled dream.

If what a prophet proclaims in the name of the Lord does not take place or come true, that is a message the Lord has not spoken. That prophet has spoken presumptuously. Do not be afraid of him” (Deuteronomy 18:22).

-----------------

The above verse is a false prophet verification test, let's see if this test qualifies or nullifies Joseph from the bible as a true prophet 

( Note this is only according to Biblical standards Muslims without a doubt believe Joseph Pbuh as a Prophet of God) 

Then he had another dream, and he told it to his brothers. "Listen," he said, "I had another dream, and this time the sun and moon and eleven stars were bowing down to me." (Genesis 37:9)

It's pretty simple to understand the text, Joseph had a dream where he saw his father mother and 11 brothers bowing down to him, his father in verse 10 confirms this. So its only fair to say Joseph's dream was a PROPHECY that his parents and siblings will make obeisance to him,  but the question is did they lets find out.

Now Joseph was the governor of the land, the person who sold grain to all its people. So when Joseph's brothers arrived, they bowed down to him with their faces to the ground. (Genesis 42:6)

He said, "Swear to me." So he swore to him. Then Israel bowed in worship at the head of the bed. (Genesis 47:31)

What happened to Rachel his mother? the Bible says she passed away as fond in Genesis 35. from all this we can conclude that Joseph's prophetic dream was never fulfilled.

On a similar note, Rabbi Berekhya said: Even though part of a dream is fulfilled, all of it is not fulfilled. From where do we derive this? From the story of Joseph’s dream, as it is written: “And he said: Behold, I have dreamed yet a dream: and, behold, the sun and the moon (Talmud Berakhot 55a:17)

and eleven stars bowed down to me” (Genesis 37:9), and at that time his mother was no longer alive. According to the interpretation of the dream, the moon symbolizes Joseph’s mother. Even this dream that was ultimately fulfilled contained an element that was not fulfilled. (Talmud Berakhot 55b:1)

Does that make him false prophet according to Deuteronomy 18:22?
