You are repeatedly ducking the relevant facts that have been pointed out to you.
(1) The point is that seekers feel so overwhelmed with awe by the bestowal of the Spirit's power that they fall, both forward and backwards. Sometimes they fall forward to break their fall ahd the roll over on their faces. Hence the defamatory term "holy rollers."
(2) John Wesley, the father of Methodism, made it clear that falling under the power can be a natural emotional reaction to the powerful physical stimulus of being overpowered by the Spirit.. it also applies to the experience of Presbyterians, Methodists, Congregationalists, and Baptists in the Great Awakenings in the 18th and 19th centuries.
