None of this is rocket science, although it may seem that complicated.
An earnest investigation of mystical phenomenae (and not all things called that are even close) as studied and confirmed by the Church over many centuries, such as the magnificent discussion from Fr. Adolph Tanqueray's "The Spiritual Life" (TAN has an edition, I am told) will clear up many questions.
99.99999% of any and all such absurd claims are pure bunk, at best.
That is not to say that aesthetes and other exemplary Catholics do NOT ever receive communications from the Great Beyond, nor are the young exempt from any such favored possibility. However, it is only the Church Herself that has authority to confirm or condemn such claims.
She has done so and will continue to do so. And no one else may. Period.
The number of heretics, bigots, idiots and others who have claimed a "divine mandate" have caused revolutions, wars, schisms, mayhem, and in cases like Medjugoogo, criminal enterprises to cash in, big time, for centuries.
And from this ridiculous swirl of madness not a few traditionalists have not been found exempt, either. A prime example is the infamous "Poem of____" by Valtorta, an heretical concoction still in print despite the efforts of the Vatican, going back decades, to utterly suppress its mad fiction.
