Can you explain what is happening when I feel physical sensations during prayer?

Sometimes during prayer or a priestly blessing, I can feel a physical sensation, such as a power field “hitting me”, even pushing me backward. Can you explain this phenomenon in physics terms, or is this something from a heavenly dimension that is not explainable in scientific terms? I just finished reading your book “Finding True Happiness” and it has been a great encouragement for me. Thanks! Connie. Orange County, California #fsuniverse www.ewtn.com/fr...
