People in our society believe all sorts of things.
A sizable number have reported being abducted by aliens. Some swear to have seen UFOs. We have people on our media who seem to believe in angels and others who believe in conspiracy theories.
I won't pick on anyone's beliefs or hold them up for ridicule for their sincere and ecological beliefs. If whatever they believe allows them to interact with society in a productive way, all the better for them, and for us if they share their perspective.
Now... on to the mentalist perspective. Surely the Platonic notion of ideals remains with us today, as with CG Jung's notion of a collective unconscious. Today we have an almost tangible zeitgeist present in our film industry. Film may be the common language and mythology in our society. If we share the same mass media and share the same mono-culture, then we are all but connected in our thoughts and only separated by circumstance.
Add a few deliberate, provocative and (for now) unsubstantiated assertions to the above and we are all set to enjoy Mercury in action or to attend events where the zeitgeist can act almost directly.
Identical twin mentalists? A wedding band that sealed more than just a legal marriage?
Sure, why not a couple with a mental link?
