Revelation among other books does provide examples of men dreaming dreams, which are otherwise not specified, which I and many others take to mean prophetic dreams otherwise it would be insignificant rather than noteworthy in a book largely dedicated to prophecy.
You apparently believe that all prophecy that can ever be is plainly written in scripture. I believe prophecy is not finished otherwise we'd not require the instruction provided scripturally, regarding how to test a purported prophet of God as well as the consequence of falsely claiming to be such.
We'll just have to agree to disagree.
There’s only one person claiming to be prophetic here and that is the author of this Tsunami hit.
Since you say these dreams are not specified in God’s Word (and I agree), you should probably heed some extreme caution around something like this if you want to rely on the Holy Spirit for Truth.
All prophecy that God wanted us to know is plainly written. God wants His children to know about real events that will happen, that’s why it’s there. The Bible is about 30% future prophecy. This USA Tsunami account about a revival isn’t in there, so I’ll take my discernment and toss it up to more End Days Apostasy - which is thicker than ever these days.
