[[ Dear Sister. Are spiritual directors familiar with mystical experiences today? Is it possible that a directee would have experiences that were really from God but that the director doubts? ]]
If a client has experiences s/he calls mystical and is sure are of God I may or may not agree. If I have doubts about these experiences being of God I am apt to kind of bracket them off in my mind, hold them in prayer, and wait for the fruits of such experiences to become evident. (I will also do some personal work to be sure there are no personal reasons which bias my perceptions in this matter.) Occasionally I will tell a person the reasons I doubt these experiences are of God or indicate what they remind me more of, but usually I will not do this. In either case I will temporize and try to assist the person to attend to what changes in them along with the shifting way they view the world and God as a result of these experiences.
The focus cannot remain on the experiences themselves in any case; it must shift to God and to what God reveals of himself in these ways. The person experiencing whatever it is must move from this original focus to wisdom. They must integrate whatever they have been given and grow in "grace and stature" as persons in Christ --- as the saying goes. Nor does this happen all at once. Again, if an experience is of God then it will be given for a reason and one will judge matters according to the fruits of the experience, both immediate and more mediate. Can I be mistaken? Of course. Similarly there are probably people doing direction today who are ignorant of such things or even closed to them. Still, if we continue to focus on the fruits of experiences and work hard to stay out of the Spirit's way in our work with a client, our own initially mistaken opinion will not make a lot of difference.
However, I don't personally know any working directors who are not regular pray-ers; this means they have ordinarily had occasional mystical or peak experiences themselves. Beyond this most have had some advanced education in spirituality or theology and many in psychology or pastoral counseling as well. All the directors I know have also worked with people who have had genuine mystical experiences --- though these tend not to be particularly unusual or frequent. They ARE personally striking and ALWAYS life changing however! Most of us have heard God speak to us from time to time and may have experienced ecstasy. Occasionally there might be something we identify as a vision. Many of us have moments of profound intellectual insight which may be tied to some kind of imagery. What tends to be true of all of these experiences is that the person will return to them again and again to continue to allow it to nourish them and become a source of real wisdom. Each experience is a doorway to the infinite, a way of being taken hold of by mystery. Each experience allows us to enter this realm again and again. Thus, this is another reason they are not usually frequent and certainly not predictable.
Are Directors More Secular and Skeptical of Mystical Experiences Today?
[[Since you do direction today would you say that SD's are more secularized or less open to mystical experiences today?]]

The bottom line here is that it is true that spiritual directors today do not accept as authentic (or at least are skeptical about) some phenomenon that were once automatically seen as Divine. But this does not mean a rejection of the truly mystical or even the miraculous. Mystery and miracles are real. Miracles reveal the deepest order of the cosmos as does Mystery. We expect this deep dimension of reality to be experienced by every person who opens herself to it and, of course, we are open to such experiences ourselves. Still, to reiterate one last time, the authenticity of any experience can only be measured by its fruits: do these experiences build community, do they increase a person's capacity to love in real and concrete terms; is one made more generous, self-sacrificing, hopeful, whole, and happy through them? If so, then we are dealing with something that is truly of God; otherwise judgment must be withheld until the fruits (including the bad fruits of division, selfishness, isolation, etc) become clear.
