HI
personal experience
Gemini have this problem just like the sign would suggest but Libra men actually have a cycle like a woman's cycle that gives that illusion of PMS. no matter how much i try to rely on the cards there are some personality characteristics that just always hold true in astrology.
now that put aside i have found that people with psychic abilities do have a double personality. that comes with being sensitive to things around them advanced forms would be a empath that doesn't have control of their gift.
peace always
