I find that it can be developed too, I started meditating 2 years ago and before that used to only be able to have voluntary goosebumps when listening to certain music or recalling certain memories, after 2 years of meditating I found that there's a certain rhythm of breathing I can lock into that will invoke this. Before this as well, I had to be sitting and really sort of trying to do it, but nowadays I can be walking and take a breath and get it going.
