That is not "mysticism " and no where does God tell us that it is acceptable in the NT ... The church has the scriptures which speak for God.. there is no more to add to that. God closed the scriptures when His revelation to men was ended...
You need to stop grouping Christian mysticism with non Christian mysticism
And how does it differ? Out of body travel, visions, secret knowledge.. meditation /emptying your mind .. looking at the inner self??
Catholic Mysticism grew out of Pagan/eastern mysticism..
My goodness that is a mouthful. For you to be able to state that implies that you have a thorough knowledge and understanding of pre-Christian paganism, eastern mysticism, and Catholicism. You haven't yet demonstrated or shown any competence in any of the three. Where did you study any of these?
yes it is, it came to you from man from God who is a mystery
And how does it differ?
Christian mysticism is Christ centered and Non Christian mysticism is self centered.
Of course there is the NA movement which has been easily exposed by the Catholic Church since most if it comes from old heresies
Perhaps this might help you.

What is Early Jewish and Christian Mysticism?
http://www.marquette.edu/maqom/definition.pdf
Excerpt..As a word, “mysticism” has a notorious reputation. Its polymorphic associations make precise meaning difficult to isolate, especially across cultures and eras. It is often used as an antonym for so-called “rationalism,” associated with so-called “supernaturalism,” in contradistinction to our contemporary scientific view of the world. Broadly speaking, it has come to describe for us organized practices used to illicit direct contact with the divine.
As an “-ism,” “mysticism” is not an emic word, a word actually used by ancient people to describe their experiences. It corresponds to no single term in the ancient literature. In fact, when the early Jews and Christians describe their mystical experiences in a single word, they do so most often by employing the term “apokalypsis,” an “apocalypse” or “revelation.”
