My three years as a parish priest convinced me of many things. One of them is that extraordinary spiritual phenomena are not as rare as we often think. Many people have experiences akin to visions, locutions, the voice of God giving consolation or direction in dreams, among many other sorts of things. Folks just don't talk about such things that much, either because we have been taught to disbelieve them, or because we don't want to be made fun of or labeled. On the positive side, such experiences represent a kind of intimacy with God, and intimacies are always secret in one way or another.
Extraordinary experiences can be a great encouragement or consolation, but they can also be the occasion of certain temptations and dangers.
Here's one that has arisen in my own life in recent months: when I receive the Host at Mass, I often bring my joined hands to my face for the moment of meditation (per the older rubric). Sometimes, just for a instant, I notice on my fingers the smell of the Sacred Chrism. Of course the anointing of my hands from my ordination is long washed away--on the natural level--but once in a while, there's the smell.
Why should this happen? The anointing is still there on the spiritual level. As I once heard in a humorous but perhaps helpful analogy, the anointings with Sacred Chrism which we receive in Baptism, Confirmation, and priestly ordination penetrate the surface and end up on the bones, as in the case of Wolverine's adamantium-bonded skeleton. (Perhaps it seem silly, but this is an image young people can get.) Sacraments are outward signs of interior grace, after all, but the interior and exterior are mysteriously joined in the mystery of the Incarnation itself. Why am I given this little gift of seeming to notice, on the natural level, the supernatural grace of the sacrament signified through the anointing of my hands? Perhaps it's an encouragement.
But we can't let such encouragements turn into distractions. I can't be thinking about all this during Mass, apart from momentary interior acts of faith or gratitude. Most of all, I can't look forward to such a thing or become disappointed if I don't get it. Grace, when grabbed for, disappears. God refuses to be a commodity, and resists any way that we try to come at the spiritual life with a consumer mentality.
