Atheism is irrational.

[Neo-Scholastic]

With all due respect, I think it is most atheists who are unwittingly playing with semantics.

Well, I personally think that gnostic visions fall into a different category: theophany.

Do you see the irony there?

Your post verges on deceptive editing since each phrase refers to completely different issues.

Be that as it may, the key distinction is that miracles affect the external environment. Theophany falls into the same category as dreams, visions, epiphanies, and even peak experiences, all of which are subjective internal experiences.
