Only once in a clear manner. I think it is possible that the human mind can perceive more than with the senses alone, but I accept it is speculation. People who try to work as professional psychics have a burden of performing on demand, which I think leads to a foundation of psychological tactics that provide an appearance of insight, but are not examples of the actual phenomenon. The general to specific tactic used a lot a few decades ago with the public popular psychics like "I am sensing a great loss related to the letter 'K'", and then people say "Yes, my aunt Kate died last week!" The second tactic is speaking in non-falsifiable ways. "I can see you surrounded by the color green in the summer which means 'xyz', and then later in Fall there is an engulfment in golden shades". Presenting the generality or the non-falsifiable notions and allowing the client to respond with details is a social communication tactic and not necessarily extra-sensory insight. I have been generally skeptical about it.
I did go to an elderly psychic and I did not help him at all. He gave a lot of very specific accurate information that could not happen statistically. I have had a few experiences myself that go beyond statistical anomaly like I kept hearing the phrase "Your house sells for [$insert dollar amount]" and then it did. The offer was over the asking price, so completely bizarre that I heard that number in my brain ahead of time. It was an exact dollar amount, so statistically incredible if a random correlation. I feel connection to people who have passed, and I think humans in general likely have some of this ability, but it is difficult to hear. It is like reality is a huge stew and some of the information is from the external world, some is from our memories, some is from our subconscious symbolic language, and some could be external to us on a metaphysical plane. It is difficult to parse out what is what and be definitive, but it is important to me and something I spent countless hours exploring.
