I attended a week-long workshop at the Monroe Institute in Virginia back in the early 2000s. I did their flagship "Gateway Experience" program. I didn't have any OBEs, but it was a very worthwhile program that has enhanced my meditation for decades. It also had a very pronounced impact on the quality, and vividness of my dreams, as well as markedly improving my dream recall ability and I did achieve one OBE in the aftermath of my participation in the program. It wasn't a profound, mystical experience. It felt like a dream, but I was able to confirm that what I experienced actually happened IRL.
