Any experience not backed up by Scripture is an extra-biblical account. That's why it is referred to as an experience, and is not found in Biblical revelation.
I mean, that's what the an experience is that has no place or backing, it is "extra-biblical" something that is "outside Scripture." Your related story and attempt to validate it as from God, and not extra-biblical is non sequitur. You're making this experience you heard about as true as Scripture and/or of God because you and others "heard it." Scripture is the test, not experience, not hearsay.
We could show how inconsistent and flimsy your argument of validation is by validating Fatima as well, all from your same criteria. Stories have no authority. Peter spoke of how Scripture is authoritative over experience, 2 Peter 1:16-19 &c.
This is why I will remain Sola Scriptura. Your position is not Sola Scriptura, it is "exta-biblical."
(I am making this post as an admonition for others who desire to remain thoroughly Biblical, as most certainly EG will not accept this clarification nor see his basic error, and be corrected.)
