Although I agree with some of what you say in your post, I also have to point out that when you distinguish between so-called "astral" events and "spiritual" ones, you are in a sense showing the "veneer of superiority" you mentioned as a distinguishing feature. Something of a Catch-22, no?
In my opinion, based on personal experience, psychic events, "divination", and such aren't particularly spiritual. In fact, they are considered
useless in some spiritual disciplines. In Christianity, they are generally considered of the devil. The exception is that some Christian sects
believe in "Word of Knowledge", that the Holy Spirit can sometimes show a person certain events to come. However, other sects consider this Word of
Knowledge to be demonic influences trying to lead a person into error.
According to Hindu and Buddhist beliefs, the powers that sometimes arise as a result of meditation and spiritual practices are more of a hindrance
than otherwise. This same belief is found in some mystical sects of other religions - in particular, in the Hasidic tradition of Judaism, in some
mystical Christian groups, and within the Sufis is Islam. Unusual powers or gifts of any sort seem to be regarded with great suspicion, and in
general are considered little more than an unimportant byproduct of spiritual practices.
There is a story of a student who was performing intense meditations. He ran to his teacher and told him, "Now, when I meditate, I see the angels of
the Sun pushing his chariot across the sky!" The teacher told him, "Keep on meditating; it will go away".
It seems to me that the Astral Circus may have its place. Western culture is severely materialistic. Many people have no inkling of Spirit, no
concept of reality beyond what can be sensed by material faculties - touch, sound, sight, smell, taste. Anything else, to them, is completely
nonexistent, false, imaginary. For such people, it may be asking too much to expect them to leap from pure materialism to spiritual belief. Perhaps
they need to see a few non-material "signs and wonder", just to get them to rethink their fundamental assumptions.
Of course there is the danger of getting hung up on the "astral circus". But there is always a danger of getting hung up anywhere along our
journey, no matter where we are at the moment. My experience so far has been that if you think you've "arrived", you haven't. You're just
momentarily stuck at some point, and will eventually continue your journey.
