I posted this video in another thread. Richard Martini is a filmmaker who started interviewing people involved in past life & between lives hypnotic regression and filming sessions (he mentions working with Scott De Tamble). He was struck by recurrent commonalities, as well as being able to verify the information reported regarding past lives (including when he accepted to undergo it himself). He's since brought that material together with NDEs and recently mediumship, and he released the film
Flipside: A Journey to the Afterlife (2012), and four related books since. He talks about it in this inaccurately-titled IANDS conference video (between 7:30 and 20:17 and then later on the video again):
The thing I'm wondering about is that Martini, who also interviewed Bruce Greyson, Mario Beauregard, and others, brings up how Bruce Greyson repeated to him the Ian Stevenson line that you can't study past-life regression scientifically, a point Martini seems to automatically accept, which is why he then also studied NDEs and looked at the similarities with past-life regressions, etc. But isn't that a questionable claim? Yes, regression therapy has more than its share of traps - potentially false memories, potentially leading the patient, etc. - but couldn't some of those be controlled for in some fashion? Like leading the patient, a point Martini was keen to observe and check. Sessions could be filmed (as Martini did), there could be strict guidelines in an experiment as to what a therapist isn't or isn't allowed to say.
More to the point, if Martini and others (including Newton reportedly) are able to verify that the data reported in past lives can be checked (in many cases) and is found to be accurate and that at least in some cases it is possible to rule out the patient having been able to know this information, to me that seems to open up an avenue of potential scientific experimentation.
There might be a lot of challenges and difficulties involved in setting up a sound experiment structure, maybe in the end insurmountable, but that's a different point than dismissing the whole field as scientifically invalid from the get-go.

BTW, lots of videos with Scott De Tamble at Richard Martini's youtube channel, like this one:
