Yes. He starts off Act 5 talking about a dream which he believes prophesies happiness for him and Juliet.
He dreams that he died, and Juliet kissed him and he came back to life.
In Act 1 Scene 5, Romeo's dream (near the end of the scene) is him predicting his own future. He dreams that something bad is going to happen to him. Romeo isn't in Act 4. Hope I helped!!
Presumably you mean his "Queen Mab" speech in Act 4, which is about dreams, and how different people have dreams. It is a long speech with curiously little point to it. As Romeo says, "Thou talk'st of nothing."
In Shakespeare's play "Romeo and Juliet," Romeo believes in the importance of dreams and fate. In Act 1, Scene 4, he says, "I dreamt a dream tonight." He interprets his dream as an omen that will lead him to his destiny, showing his belief in the role of dreams in shaping one's future.
Mercutio says this to Romeo in Act I Scene IV of Romeo and Juliet.
Act 5 starts with Romeo in Mantua, talking about his dreams. Nobody pays respects to Juliet until Paris does, later on in the act.
You have misquoted. The phrase, from Act V Scene 1 of Romeo and Juliet is: "If I may trust the flattering truth of sleep, My dreams presage some joyful news at hand." And what Romeo is saying is that he has had a pleasant dream and he feels good about it. The dream tells him there is some joyful news at hand. But he is not sure he should trust it, because the truths of dreams can flatter, can tell you what you want to hear. The "flattering truth of sleep" means dreams that tell you what you want to hear.

Romeo and Juliet decide that they want to marry each other, Romeo arranges it and by the end of the act they are married.
Tybalt calls Romeo a "villain" in Act 3, Scene 1 of Romeo and Juliet.
Romeo was banned because he killed Tybalt.
