My sister went to a medium

This past weekend my sister called and said she was just returning from visiting her medium.  I want to believe with my heart that my sister spoke to my mother via a medium but my mind fights it as true.  It is like a horoscope - you can read it and construe it to fit your life but I am not always sure that it's accurate and true.  Today my horoscope says,

"The year ahead is excellent for close relationships, learning, skills training, and organizing your life, dear Aries. While career objectives and long-term goals are in focus as you begin 2017, you're also giving due attention to health and wellness. You may be slowing down a little and enjoying a more leisurely pace than usual. Your humanitarian impulses are strong today, and you can feel particularly hopeful about new plans and what's on the horizon. You're learning that drawing upon patience gets you places, and you'll enjoy a beautiful balance between practicality and innovation in the coming year. You are highly intuitive right now, particularly about which attitudes or directions you need to leave behind you so that you can move forward.

 Creativity: Good ~ Love: Good ~ Business: Good

After reading this horoscope - I think yup, that's dead on.  So then I want to believe that my sister was hearing from my mother.  The medium told my sister that my Uncle John would be joining her in the near future so I guess that will really tell us if she is spot on or not.   

Do you believe in mediums?
