Past Life Experiences In Breathwork

In one session a few years ago, a participant who had been afraid of water his entire life without knowing why, had an experience during breathwork of living in the 1700’s and drowning. It was a particularly difficult experience, feeling like he could not breathe, fighting for air, etc but, he went through it and, he has not been afraid of water again since then. Was it really a past-life experience? There is no way of telling. However, what we do know is that that is the way that his psyche thought was the best way to bring him the breathwork experience that would resolve his phobia.
