There are a number of stars on this, off the top of my head, Acrux, Mimosa, Sadalmelik, and many others. People that I know of who had experiences like Kundalini rising and others never failed to have one.
Also, though I dont believe much in trans-saturnians, it is true I remember time ago I had the Kepler, featuring astrosignatures, there were some 30 or 40 charts of psychics and related bipedals, and seemed to me some 60 % of them had Mercury-Neptune. Maybe someone can double check it. I am thinking of the occult here, as in doing it, doing things, as different from just researching it.
For astrology you have many threads always in astrology fora and more stars, for example Deneb Adige, Alphecca I seem to remember. There was a conversation in Skyscript on of course how predisposed they were to astrology, and being into traditional, was put down to great Mercury, Virgo and stuff. But then they said, look at that, Evangeline Adams, Dane Rudhyar and cant remember who else, have Mercury in Pisces which is very bad. I say they were missing it was always at the beginning of Pisces, where there are a number of mercurial stars which in past times were in Aquarius. I would place my bet on Mercury with any important mercurial star, then more things.
Something that I ve noticed is that you cannot normally do well in "both sides", people who do well in "the other world" appear to me to be liable to delusions over here. In that respect, the occult and astrology would be different. If you look into all siddhis, for example, it is all about how well you do in the other side. For example, clairvoyance/remote viewing is nothing but clear astral vision. To access clear astral vision, you need dissolution of ordinary mind, so that the brains enters a secondary state of functioning, which exists, though most people dont know about it. Therefore I would give some credence to normal stuff like 8th house, Pisces, etc.
If you believe in Morinus' determinations theory, whereby planets mean only what they are "determined to", i.e. different things for different natives, unless angular where they get back there basic significations, then I guess you depend on good or weird stuff going on on the mind axis, 3rd-9th.
Good luck to you with your spooky things anyway
