Allah's Messenger (ﷺ) said, "If I stayed in prison as long as Joseph stayed and then the messenger came, I would respond to his call (to go out of the prison) ."
I heard the Prophet (ﷺ) saying, "Whoever sees me in a dream will see me in his wakefulness, and Satan cannot imitate me in shape." Abu `Abdullah said, "Ibn Seereen said, 'Only if he sees the Prophet (ﷺ) in his (real) shape.'"
The Prophet (ﷺ) said, "A good dream is from Allah, and a bad dream is from Satan. So whoever has seen (in a dream) something he dislikes, then he should spit without saliva, thrice on his left and seek refuge with Allah from Satan, for it will not harm him, and Satan cannot appear in my shape."
The Prophet (ﷺ) said, "I have been given the keys of eloquent speech and given victory with awe (cast into the hearts of the enemy), and while I was sleeping last night, the keys of the treasures of the earth were brought to me till they were put in my hand." Abu Huraira added: Allah's Messenger (ﷺ) left (this world) and now you people are carrying those treasures from place to place.
Allah's Messenger (ﷺ) said, "I saw myself (in a dream) near the Ka`ba last night, and I saw a man with whitish red complexion, the best you may see amongst men of that complexion having long hair reaching his earlobes which was the best hair of its sort, and he had combed his hair and water was dropping from it, and he was performing the Tawaf around the Ka`ba while he was leaning on two men or on the shoulders of two men. I asked, 'Who is this man?' Somebody replied, '(He is) Messiah, son of Mary.' Then I saw another man with very curly hair, blind in the right eye which looked like a protruding out grape. I asked, 'Who is this?' Somebody replied, '(He is) Messiah, Ad-Dajjal.'"
Allah's Messenger (ﷺ) used to visit Um Haram bint Milhan she was the wife of 'Ubada bin As-Samit. One day the Prophet (ﷺ) visited her and she provided him with food and started looking for lice in his head. Then Allah's Messenger (ﷺ) slept and afterwards woke up smiling. Um Haram asked, "What makes you smile, O Allah's Messenger (ﷺ)?" He said, "Some of my followers were presented before me in my dream as fighters in Allah's Cause, sailing in the middle of the seas like kings on the thrones or like kings sitting on their thrones." (The narrator 'Is-haq is not sure as to which expression was correct). Um Haram added, 'I said, "O Allah's Messenger (ﷺ)! Invoke Allah, to make me one of them;" So Allah's Messenger (ﷺ) invoked Allah for her and then laid his head down (and slept). Then he woke up smiling (again). (Um Haram added): I said, "What makes you smile, O Allah's Messenger (ﷺ)?" He said, "Some people of my followers were presented before me (in a dream) as fighters in Allah's Cause." He said the same as he had said before. I said, "O Allah's Messenger (ﷺ)! Invoke Allah to make me from them." He said, "You are among the first ones." Then Um Haram sailed over the sea during the Caliphate of Muawiya bin Abu Sufyan, and she fell down from her riding animal after coming ashore, and died.
