Goosebumps are not related to the the spiritual process. Energy movement in the body which affects body “prickling” “pressure” etc. are related to the cleansing of the body in relation to cleansing of the mind. It’s pretty regular phenomena even if you just practice anariya meditation.
Physical goosebumps are related to clenching of perineum, pleasant sensual feeling in relation to six senses or situation when you doing something “with flow” and you see how good you are in that flow.
The spiritual aspects of that I had many as I practice meditation by 10+ years by now insistently so I had high spectrum of experiences which are different then just “goosebumps”. I can not tell relation of energy in the body in Buddha thought so maybe Lal can explain it. You can do just simple exercise to feel energy in the body by moving your attention (as it would be a dot) and looking into your hand. Start to make spiral movements with your intent and thoughts that you move your mind like you would paint on hand with attention. Make spirals from smaller to higher and back to the point zero counterclockwise and clockwise. You must move back to the point zero or you can create problems with your blood flow or nervous system in that place. As you can experience our mind affecting something “invisible”. So we can imagine how bad thoughts and kamma can make some changes on that level which we are not even aware in our everyday life.
