We all know that dreams of any nature can occur! I've had some rather wild ones myself, being chased through deep water, riding a rapidly decending elevator that has no sides, clinging to the floor! We have them, but put no importance or stock in them! Our natures are sinful, not to be relied on!
The Word of God is that one valid thing in which to put our whole trust and reliance, not on our experiences! Who should care if I have this dream of ascending in a white gown into the clouds, calling others to come with me! Ridiculous and also dangerous stuff there!
When God closed His book, He most clearly stated that He did exactly that! Again our focus is on God, what He does, who He is, what He has clearly stated for us to do and to be concerned with!
People who become very concerned with dreams and visions and experiences are walking a dangerous path! He told us to 'study to show ourselves approved unto God, a workman that needeth not to be ashamed, rightly dividing the Word of Truth!'2 Tim 2:15
He also instructed that we examine ourself to be sure we're in the faith! When we do so and find a growing interest in dreams, visions, experiences, deathbed occurences we immediately go back to God's Word and seek His face, His truth!
Anyone can dream anything but I certainly dont want to state my eternity on such! If it should drive you back to study the Word, then it would be a good thing, only then! The great danger is that it encourages an 'other than bible focus'!
