I'm so happy to find this! I also created an account here to respond. I've been able to get this deep relaxed feeling for as long as I can remember but never really thought it was anything special until recently. I'm 39. But yeah, for me, it starts in the thighs and spreads out from there. It almost reminds me of that feeling you get going down that big initial drop on a roller coaster. Almost a tingly weightlessness. I'm super curious about what that is. Are we able to leave our bodies at will, because that's almost what it feels like. Lol.
