I will share my own experience on this. Obviously there is no way to verify this but this is why I believe in psychic ability.
Two years ago when I had a compelling experience that I couldn’t dismiss as mere coincidence. I had a vivid dream where my grandmother visited me. In the dream, she was wearing her favorite blue dress that she wore often in the summer. She hugged me and told me not to worry. That evening, my father told me my grandmother had died the night before. I was shocked. It really changed my view on that sort of phenomena. It really was unexplainable.
