Two items of possible interest.
Recently I had a telephone reading with medium Georgia O'Connor. This was only the third time I've sat with a medium. While I prefer to keep the details private, I found the reading strongly evidential and emotionally meaningful. I personally feel much more convinced of life after death than I did before. Some of the material that came through was not only accurate and specific, but seemed so eerily on-target that I found myself thinking, "I can't believe she's actually telling me this." I don't think any amount of advance research could explain the results, and "lucky guesses" - while impossible to rule out - seem like an inadequate explanation also.
Of course, I can't guarantee what other people's results might be. For those who may be interested, Georgia O'Connor's Web site is here.
Michael Tymn's blog is one of the few paranormal blogs I read regularly. Currently he's doing a fascinating series on materialization mediumship. Never having witnessed these phenomena first-hand, and knowing there has been much fraud in this area (not to mention some very fake-looking photos, like this one), I remain somewhat skeptical. But the eyewitness reports cited by Michael are certainly impressive; if I'd seen what they saw, I would be a believer too!
