I found this article here on twin flames
http://www.astrostar.com/twinsouls.htm They did a research on Twinsouls and compared astrological signatures - of course those people thinking they have met their twinsoul could have been clinging to an illusion, so I´d see this as a nice article, but not the last word of all
Some quotes:
"It seems so far that many twin souls have their sun signs in the same element."
"The big three (sun, moon, rising) are of the same element or in compatible (sextile) elements. If one person has two fire and one air, the other person does too. They are less likely to be twin souls if, say, one person had one earth and the other didn't."
"Rising signs (might be) the same with the rulers in the same element."
"The moon of one is conjunct an angle of the other's chart."
"One of these seem to be a cardinal rule so far: Sun is conjunct the moon of the other; moons are in the same element, or moons are in the same sign."
"Twin Souls meet when there's a personal planet progressed to the sun/moon midpoint on each natal chart."
"There may be a preponderance of aspects, especially by trine, from the personal planets of one's natal chart to another's Midheaven."
"Many planets of one person's chart fall into the angular houses of the other's natal chart."
"The numbers 6, 9, 15, 24, 27 seem to be involved with twin souls birthdays. Twin Souls often meet on one of those days, too."
I don`t even know why, but I compared these "findings" with the chart of this "dream-guy".
- our Sun`s are in the same sign, so we both have a Fire-sun
- if he indeed has an Air-ascendant, our big three`s are all compatible, both having two fire signs and one air signs:
Me: Sag-Sun, Aquarius-Moon, Sag-ASC
Him: Sag-Sun, Sag-Moon, Libra-ASC?
- Rising signs are probably not the same (noone could tolerate someone with Sun, Moon AND ASC in Sagittarius I guess); but I can`t decide this one, for I am not certain about his risign sign
- His Moon is not conjunct an angle in my chart, of course my Moon still "could" be conjunct his IC (Libra-ASC), DSC (Leo-ASC) or ASC (Aquarius-ASC).
- his Moon is conjunct my Sun (in my angular 1st house)
- At the time of our very first encounter his progressed Mercury and Sun were conjunct MY Sun-Moon-midpoint and my progressed Mars was conjunct HIS Sun-Moon-midpoint
- now, this year my progressed MC is semisquare his Sun-Moon-mp
- if he hast the Libra-ASC I think he has, his progressed MC will be semisquare my Sun-Moon-mp, but well, I don`t know that
- if applying solar arc, his directed Moon will be conjunct my Sun-Moon-mp this year
and my directed Venus will be semisquare his Sun-Moon-mp
- regarding MC_aspects (of course I can only speak for my MC)
Not so many; conjunct his Karma, opposite his Osiris and Ceres
- planets in angular houses:
his Sun, Moon, Mercury and Neptune in my 1st house
- regarding the numbers 6,9, 15, 24, 27
The first encounter took place on 3rd june (6) 2006;
my birthnumber reduces to a 33 / 6
His birtnumber reduces to a 3
I know this is just toying around, but it is interesting nervertheless
