Read the history of the early Church's attitude towards the Revelation of John. Who accepted it? Who rejected it? It took several centuries before it was (almost) universally accepted. And I mean centuries after Athanasius produced his list in 367 (which was almost 300 years after Revelation was written). And there is no indication that his Egyptian church accepted Athanasius' list.
Several Apocalypses ("Revelations") were in circulation; some Churches accepted one of the others. We know of the: Apocalypse of Peter; Coptic Apocalypse of Paul; Apocalypse of Paul; First Apocalypse of James; Second Apocalypse of James; Apocryphon of John; Sophia of Jesus; Letter of Peter to Philip; Apocalypse of Mary.
In this context, I will mention another book that includes visions, was considered by some churches as Scripture and is included in the Codex Siniaticus: and that book is "The Shepherd of Hermas".
Therefore, before relying on anything that Revelation might say, or be interpreted to say, first recognise that it was written to, for and about the period it was written in (end of the 1st century) and secondly ask: Who decided it should be included in the Canon of Scripture -- should it be in the Bible? How did it happen? When?
