Not all psychics or readers have the same ability or interest. Retro-cognition (past), cognition (present), and pre-cognition (future) are areas that a psychic or reader may divine and it depends on their ability and interest as to how well they can do so, if at all.
Professional readers have a code of ethics they read by and it generally doesn’t include telling people about things they can not control or that are psychically damaging to know about. My rule of thumb is this: Does it add value and benefit the person to know? If yes and it doesn’t go against code, then I will tell them and then give them ideas on how to improve a challenging situation.
Psychic readers often focus on specific areas of concern that is often decided upon by the person getting a reading. In some cases, a person (also called a sitter or seeker) just wants to be “read” in which case it’s often general information the psychic sees which they then interpret into general or specific insights for the sitter. Also, the qualities of insights are dependent upon the question and energetic openness of the sitter to the reader.
Psychic readers can read your mind if we focus our intent on doing so; however, if we did that with everyone all the time, we would become exhausted and require mental health assistance. Myself, I am personally not interested in that! Also, any professional reader will ask for permission instead of invading your privacy. Having said that, some things like intuition and face reading become automatic but one normally tunes into it for brief periods of time and only when necessary. Also, if someone doesn’t want to be read, they can’t be — it’s that simple.
