Yeah that is interesting. I imagine if I heard someone saying that type of thing I would ignore them because it sounds silly.
However my personal experience with the subtle energy in my body is anything but silly. Sometimes I just have to lie down for a couple hours and let it do it's thing while I breath. It can be really overwhelming.
I used to interpret it as anxiety, but I've managed to find enjoyment in it now. It could be old patterns releasing, or meridians sorting themselves out. I have no idea tbh, but it does end up feeling like an upgrade when it's over.
I've noticed the effects are greatly amplified if I haven't expelled life force over longer than a one week period.
