Yes he has through the scriptures, the scripture is not new prophecy. I would think confirming we have heard the existing would be a sign that follows, the prophecy that leads confirming we have heard his words of prophecy. Not new prophecy as that which adds to the finished book. Same applies to pastors they can change their minds at the last moment . I think dreams are a way to heal of psyche as common grace given to everyone.
Interpreting a dream could lead to a good outcome or one not so blessed. But is never a source for hearing God as evidence a person is with Christ. Everyone dreams everyday inspired by their own fleshy minds.. No dream activity for more than 72 hours a person begins to become confused . Dreams are like food necessary for these bodies of death.

I would offer Satan as the god of this world is the only spirit today allowed to bring a private interpretations as revelations
through a dream or making a sound as a lying wonder .
A couple verses to look at.
I have heard what the prophets said, that prophesy lies in my name, saying, I have dreamed, I have dreamed. How long shall this be in the heart of the prophets that prophesy lies? yea, they are prophets of the deceit of their own heart;Which think to cause my people to forget my name by their dreams which they tell every man to his neighbour, as their fathers have forgotten my name for Baal.Jer 23:25
Before the last new prophecy and the warning not to add or subtract from the whole, the elect are pre warned of the time period following the last book Revelation . Because they heed the warning they will not be deceived by thus says the Lord, I had a vision or a dream or another newer manner of prophecy, tongues.
And then if any man shall say to you, Lo, here is Christ; or, lo, he is there; believe him not:For false Christs and false prophets shall rise, and shall shew signs and wonders, to seduce, if it were possible, even the elect.But take ye heed: behold, I have foretold you all things.Mar 13:21
Yes, agree that regular dreams are the brain's way of repairing/recharging itself and this is all. But since the OP mentioned he dreamt of a particular book in the bible, there is no reason to dismiss it since the only outcome really is to read it, so whether it was God drawing his attention to it or him just having a desire to read it, there is no issue as it's scripture and encouraging him to read it is not me interpreting his dream at all.
As for the pastor being led by the Spirit to change his sermon last minute, for example.... little does he know the reason is because God knows someone will be walking into that church and so the new sermon might be timed perfectly for that person.
As for interpreting... not sure where you got the impression I was doing this or that I believe in this? Just as prayer is personal, between you and God... only you will know when/if He answers your prayer. No one can interpret for you, because it's between you and God. Something might happen in your life and you know God was speaking to you, but someone else would not know this. Not long ago I had a conversation with someone and he emailed me to let me know that something I said was an answer to his prayer. I have no idea what it was and would not expect him to tell me, only if he chose to, but God gave me the words to say to answer that person without me knowing at the time what his prayer had been.
There is a difference between a regular dream and a dream from God, and you will know the difference, because God makes it known to you.... and the interpretation will be clear with no confusion. My vision and dream vision were not prophetic in nature or adding to the word in any way, they were simply God communicating to me personally. I don't depend on signs and wonders and I use discernment always, so I'm not easily swayed by the devil's deceptions. I can tell you that I was not deceived by my two experiences because they were definitely from God. They were actually lessons for me personally. It's a bit like trying to explain the born again experience to someone who hasn't experienced it. Some will be so quick to say only the devil gives dreams to deceive us, but then this person has not experienced it themselves so this is all they can say. Nothing wrong with warning, of course, but not everything is automatically a lie, and in my situation the experiences were real.
As for tongues, I cannot comment on that because I just don't know much on the subject to be honest. Satan is a serial counterfeiter so I always expect to see counterfeits everywhere, especially within the churches. I personally have never spoken in tongues and would never condemn a believer or say they're lying just because I don't understand it and have never experienced it myself. I was told that my vision was a lie by a person that believes they ceased. If a person prayed and then God answered their prayer in a specific way that was made clear to them but would not be clear to others, I would never tell them they're lying, because how do I know God didn't answer their prayer?
Nothing should add to or contradict the word, and we should never depend on visions and dreams, for example. And not every dream is automatically from God either, but when it is it is made known, as sure as the sky is blue. And I don't say this to gloat, because truly He gets the glory at the end of the day, but I just wanted to confirm that God does communicate through visions and dreams, but like with everything there are always counterfeits and one shouldn't assume that every dream they have is from God, and also not depend on them. Nothing should add to scripture or contradict the word. I've never shared the dream publicly as I'm not sure anyone needs to know, and I don't want to be a target on here either. The vision I shared in my blog on here (titled "a humbling vision") as I thought maybe it would be comforting to others since the lessons were comforting to me (all of them biblical).
I wonder if God takes advantage of the time when we're sleeping, because this is when we're silent and have no distractions.
Just my thoughts.
