What is astral projecting?
I have heard anecdotes of self-healing before, it reconciles with my internal model that induced muscular relaxation + increased bloodflow via neuro-stimulation can facilitate healing and also reset any "knots" lingering around. Similar to how massaging, accupuncture and cupping can help recovery.

Seems like we are starting to tease out reproducible findings via things like Wim Hof and mass interest in yoga. I'm excited to see what we may discover about our own potential - just like how [1] debunked scientists' assumptions about pupil dilation
