My personal experience—I've done it about 4 times. The first time was pretty incredible. Not OBE or anything, but it was one of the few times I've experienced the detachment from self I hear regular meditators talk about so much. The world seemed bright and harsh afterward—I felt like a newborn. The other three times felt like nice epsom salt soaks, sometimes with sleeping. ¯\_(ツ)_/¯
