DANIEL 2:1
 

Now in the second year of Nebuchadnezzar’s reign, Nebuchadnezzar had dreams; and his spirit was so troubled that his sleep left him. [NKJV]

Nebuchadnezzar became a "Seer" but not a "Prophet," in the second year of his reign by having Dreams that could both trouble his spirit and cast away sleep from him according to this Bible verse.
 

In the last days, when God poured His Spirit upon all flesh among His People, sons and daughters prophesied, old men dreamt dreams, and young men saw visions, the world saw signs and wonders on the sun, moon and in heavens; but only those who called upon the Name of the Lord through all these shall be saved (Joel 2:28-32). But why do we need to call upon the Name of the Lord to save while or after seeing these dreams, visions, signs, wonders, sights, or hearing these prophecies, news, rumours, etc?
 

• ° We may have to pray in the Lord's Name to saved from things we are seeing and hearing in the last days. Men's heart may fail them through high blood pressure or heart-attack by what they are seeing or hearing according to "Luke 21:26." Seeing/hearing could kill:
   

[2 Peter 2:8-9] "(For that righteous man dwelling among them, in seeing and hearing, vexed his righteous soul from day to day with their unlawful deeds; ) The Lord knows how to save the godly out of temptations, and to reserve the unjust to the day of judgment to be punished:"
 

• ° We may have to pray in the Lord's Name to healed from things we are seeing and hearing in the last days.
   

[2 Chronicles 7:14] - "If my people, which are called by my name, shall humble themselves, and pray, and seek my face, and turn from their wicked ways; then will I hear from heaven, and will forgive their sin, and will heal their land."
 

• ° We may have to pray in the Lord's Name to perceive or understand from things we are seeing and hearing. Perceiving and understanding will help your conversion or repentance that obtains forgiveness of sins for you.
   

[Mark 4:12] — "That seeing they may see, and not perceive; and hearing they may hear, and not understand; lest at any time they should be converted, and their sins should be forgiven them."
 

Actually, forgiveness and healing go together. Healing means Forgiven. What is forgiven gets healing. Incurable is unforgivable.

In the top Bible verse above, brought forward:
 

"In the second year of his reign, Nebuchadnezzar had dreams that troubled his spirit, and sleep deserted him." [BSB'19]
 

Nebuchadnezzar was the seeing man, but was not a praying man. The Dreams he saw while he was still reigning as king therefore troubled his spirit and cast away sleep from him, making the greatest king then both restless and sleepless. Those dreams were doing to that king what the armies or soldiers of any nation of the world could not dare to do to such a king in his prime. Therefore, let's learn some few or four things about some dreams or visions, using these dreams of Nebuchadnezzar as case study:
 

°1° Dreams can come to a man who's already reigning or enjoying the highest ranking, highest power or epic position of life. — Some People reduced dreams to some things for those who have not arrived/reached their best or highest destination. They see dreams as some things Joseph could have while he's no body in Egypt, but stop having dreams when he became the best in Egypt. Well, Pharaoh was the best then, and yet had dreams; Nebuchadnezzar was in his second reign as king of kings, and yet had dreams. Dreams are not just for ambitions.
 

°2° There are Dreams that can trouble a man's spirit because they are stronger than the spirit of the man. — Such dreams afflicts the man's spirit or the man's soul even inside the dreams, tormenting him so that waking up from the dream is the way of escape or deliverance for the man's spirit or soul. Soldiers did not trouble Nebuchadnezzar's spirit, but these dreams did.
 

°3° As the Spirit of God casts out unclean spirits, as light casts out darkness, even so some Dreams cast out sleep. — You are already used to dreaming while sleeping, but there are dreams that if you have you will not have sleep. Sleep will not come to you because such dreams are with you. They displaced sleep, and unless you're healed by interpretation there's no sleep.
 

°4° There are Dreams that are Dream (one/single), and there is Dream that is Dreams or Vision that is Visions. — When Joseph interpreted Pharaoh's dreams, Joseph told him the two dreams were one but repeated twice in different forms to the king. So those dreams were technically one dream. But here is Nebuchadnezzar having one dream of a Statue or Image of different elements, and a Stone that struck it, and yet called "Dreams" as if they were many or more than one. Ezekiel saw Heavens opened, and Ezekiel saw "Visions of God" instead of "Vision of God" though he only saw one Vision of the Living Creatures, the Wheels, the Throne and God on the Throne.
