Acts 2:17- Now, this is what was spoken by the prophet Joel: 17 “ 'In the last days, God says, I will pour out my Spirit on all people. Your sons and daughters will prophesy, your young men will see visions, your old men will dream dreams.
Genesis 37: Joseph’s story begins- 3 Israel loved Joseph more than all his sons because Joseph had been born in Israel’s old age. So he made Joseph a special robe with long sleeves. 4 Joseph’s brothers saw that their father loved him more than any of them. They hated Joseph and couldn’t speak to him on friendly terms.
Joseph’s first dream- 5 Joseph had a dream and when he told his brothers, they hated him even more. 6 He said to them, “Please listen to the dream I had. 7 We were tying grain into bundles out in the field, and suddenly mine stood up. It remained standing while your bundles gathered around my bundle and bowed down to it.”8 Then his brothers asked him, “Are you going to be our king or rule us?” They hated him even more for his dreams and his words.

Joseph’s 2nd dream- 9 Then he had another dream, and he told it to his brothers. “Listen,” he said, “I had another dream: I saw the sun, the moon, and 11 stars bowing down to me.”Dreams (ḥalôm) in Joseph's case.

First, a dream can be how God protects his people or foretells his provision for them. God warns Laban in a ḥalôm not to harm Jacob and God uses a ḥalôm to promise Solomon great wisdom and understanding (1 Kgs 3:5–14)
13 Israel then said to Joseph, “Your brothers are taking care of the flocks at Shechem. I’m going to send you to them.”Joseph responded, “I’ll go.”Joseph goes on a few days' journey to look for his brothers, and finds them in Dothan. 18 They saw him from a distance. Before he reached them, they plotted to kill him. 19 They said to each other, “Look, here comes that master dreamer! 20 Let’s kill him, throw him into one of the cisterns, and say that a wild animal has eaten him. Then we’ll see what happens to his dreams.”
25 As they sat down to eat, they saw a caravan of Ishmaelites coming from Gilead. They were on their way to Egypt.26 Judah asked his brothers, “What will we gain by killing our brother and covering up his death? 27 Let’s sell him to the Ishmaelites. Let’s not hurt him, because he is our brother, our own flesh and blood.” His brothers agreed.28 They took Joseph out from the cistern and sold him to the Ishmaelites for eight ounces or 20 shekels of silver. The Ishmaelites took him to Egypt.
Genesis 39: the account of Joseph in Potiphar’s house.Joseph had favor-1Potiphar, an officer of Pharaoh, the captain of the guard, an Egyptian, had bought him from the Ishmaelites.2 The Lord was with Joseph, and he became a successful man, 3 His master saw that the Lord was with him and that the Lord caused all that he did to succeed in his hands. 4 So Joseph found favor in his sight and attended him, and he made him overseer of his house and put him in charge of all that he had. 5 From the time that he made him overseer in his house and over all that he had, the Lord blessed the Egyptian's house for Joseph's sake; the blessing of the Lord was on all that he had, in house and field.
Potiphar’s wife tempts Joseph but Joseph doesn't give in. The wife lies say Joseph tried to take advantage of her.
19 When Potiphar heard his wife’s story, especially when she said, “This is what your slave did to me,” he became very angry. 20 So Joseph’s master arrested him and put him in the same prison where the king’s prisoners were kept. While Joseph was in prison, 21 the Lord was with him. The Lord reached out to him with his unchanging love and gave him protection. The Lord also put Joseph on good terms with the warden.
Genesis 40- The account of Joseph’s time in prison with the Pharaoh's cupbearer and baker. 8 They said to him, “We have had dreams, and there is no one to interpret them.” And Joseph said to them, “Do not interpretations belong to God? Please tell them to me.”
He interprets the cupbearer’s dream first, and it is favorable for the cupbearer, not so for the baker. He asks the cupbearer this:
14 Only remember me, when it is well with you, and please do me the kindness to mention me to Pharaoh, and so get me out of this house. 15 For I was indeed stolen out of the land of the Hebrews, and here also I have done nothing that they should put me into the pit.”
Genesis 41: Pharaoh’s dreams
Dream 1- After two whole years, Pharaoh dreamed that he was standing by the Nile, 2 and behold, there came up out of the Nile seven good looking, healthy cows, 3 then, seven other cows, ugly and thin, came up out of the Nile after them, and stood by the other cows on the bank of the Nile. 4 And the ugly, thin cows ate up the seven attractive, plump cows. And Pharaoh awoke.
Dream 2- 5 And he fell asleep and dreamed a second time. And behold, seven ears of grain, plump and good, were growing on one stalk. 6 And behold, after them sprouted seven ears, thin and blighted by the east wind. 7 And the thin ears swallowed up the seven plump, full ears. And Pharaoh awoke, and behold, it was a dream.
8 So in the morning his spirit was troubled, and he sent and called for all the magicians of Egypt and all its wise men. Pharaoh told them his dreams, but no one could interpret them to Pharaoh.
The cupbearer remembers Joseph9 Then the chief cupbearer said to Pharaoh, “I remember my offenses today. 12 A young Hebrew was there with us, a servant of the captain of the guard. When we told him, he interpreted our dreams to us, giving an interpretation to each man according to his dream.
Joseph is brought to Pharaoh14 Then Pharaoh sent and called Joseph, and they quickly brought him out of the pit. And when he had shaved himself and changed his clothes, he came in before Pharaoh. 15 And Pharaoh said to Joseph, “I have had a dream, and there is no one who can interpret it. I have heard it said of you that when you hear a dream you can interpret it.” 16 Joseph answered Pharaoh, “It is not in me; God will give Pharaoh a favorable answer.”
Pharaoh tells his 2 dreams to Joseph saying “no one was able to interpret them.” God gives Joseph the interpretation of the dreams. 29 There will come seven years of great plenty throughout all the land of Egypt, 30 but after them there will arise seven years of famine, and all the plenty will be forgotten in the land of Egypt. The famine will consume the land, 31 and the plenty will be unknown in the land by reason of the famine that will follow, for it will be very severe. 32 And the doubling of Pharaoh's dream means that the thing is fixed by God, and God will shortly bring it about.

Second, an obscure dream provides the opportunity for someone to display God-given ability as an interpreter. Joseph is able to interpret the dreams (ḥalôm) of the royal cupbearer and baker, as well as the dreams of Pharaoh himself (Gen 40–41). In this way, the dreams also serve to magnify God in a foreign context. After Egypt’s wise men prove incapable of deciphering the dreams, Joseph succeeds; he is exalted and God is glorified (Gen 41).
Joseph’s plan:34 Let Pharaoh proceed to appoint overseers over the land and take one-fifth of the produce of the land of Egypt during the seven plentiful years. 35 And let them gather all the food of these good years that are coming and store up grain under the authority of Pharaoh for food in the cities, and let them keep it.
Joseph Rises to Power-37 This proposal pleased Pharaoh and all his servants. 38 And Pharaoh said to his servants, “Can we find a man like this, in whom is the Spirit of God?” 39 Then Pharaoh said to Joseph, “Since God has shown you all this, there is none so discerning and wise as you are. 40 You shall be over my house, and all my people shall order themselves as you command.
