Comentário sobre Gênesis 40:5

ויחלמו חלום שניהם means AND BOTH OF THEM DREAMED A DREAM — This is the real meaning (that שניהם is the subject of ויחלמו and is not to be connected with חלום). A Midrashic explanation is, taking חלום as construct case: each dreamed the dream of both of them — i.e. he dreamed his own dream and the interpretation of the other’s dream. This is what it means when it states (v. 16) “And the chief baker saw that he had interpreted well”). (Genesis Rabbah 88:4; Berakhot 55a).

EACH MAN ACCORDING TO THE INTERPRETATION OF HIS DREAM. The expression “interpreting dreams” means relating the events which will happen in the future, and he who foretells that future is called potheir (interpreter). In the opinion of many scholars the word pithron signifies “meaning.”²⁵⁷But it does not signify the foretelling of future events. And the interpretation of the verse, Each man according to the interpretation of his dream, is that each dreamed a dream consistent with the interpretation²⁵⁸The butler dreamed of wine, the symbol of joy, while the baker dreamed of a bird snatching the food he was bringing to the king, an event which signifies grief. (Tur.) which foretold the future that was to befall them. This is Rashi’s language.
Now what sense does it make for Pharaoh’s chief butler to say, “We have dreamed a dream consistent with the interpretation,” thereby minimizing the wisdom of the interpreter. Besides, Pharaoh’s dream [related later on] may not have been so, [that is, consistent with the interpretation], and Joseph would not know it.²⁵⁹Why then did he recommend Joseph as being able to interpret the king’s dream? The king had not yet related his dream, and it could be that that dream might not be consistent with its interpretation, as was the case in his own dream. Why then did he not fear for his life in recommending Joseph to the king?
Rabbi Abraham ibn Ezra says in explanation of the verse that each saw in his dream the truth concerning the future as the interpretation would indicate, meaning that it was a true dream, not the kind which comes from many worries, of which only a part is fulfilled. This is the correct interpretation.

איש כפתרון חלומו, the line means that each of them dreamt a dream which lent itself to interpretation. It did not appear to be one of the many dreams that defy making sense of it.
