Did you ever get them when praying by youself? -- That's the part I don't understand, I would think it was nervousness from speaking in front of others (which btw is something I don't typically get nervous about), but because it happens in my own room with the door shut same as it does when I'm in public or with others, I just don't understand.
I will share another event that came to mind. While still very much a Protestant, I was in a Christian book store . . there was a narrow display of books in a wood rack that I was looking over. You know how you sometimes unconsiously move your hand over the books you are looking at in case you want to pick one up? Well, as I was doing that, there was this very small book almost hiding by Jack Hayford called The Mary Miracle . . as soon as my hand passed over that book, a wind started to pour down me, with the cold sensation and shakes, and as soon as my hand moved past it, it stopped. .. I as somewhat surprised to say the least, and wondered if I had imagined it or I had just gotten the shivers .. so I moved my hand back to it, and the exact same thing happened. And the presence of the Holy Spirit became so strong . . my hand left the book again as I looked at the others around it, but when my hand passed over it again, the same experience ocured, this time stronger . . It was pretty clear that God wanted me to buy that book, so I did. This experience followed me all the way to the cashier.
Now, this book was helpful to me at the time, it was where God started to work on my understanding of who Mary is, though Jack Hayford does not accept all that Catholics believe about her perpetual virginity, etc. . . but he did go into her obedience and her example.
The experience was pretty dramatic. I don't remember having that exact same thing happen over a book before or since. . .
Sometimes God has to knock us over the head a good one I guess to get our attention!

So I am not saying this experience was because somehow I merited it, but because I was too dense to hear the still small voice of God telling me to buy it . .
Peace in Him!
