I did my very first Yoga class today. It was Ok, I need the stretching. At the end we all laid down for some relaxation time (harder to do than you'd think!) The teacher came round the class and stretched all our shoulders and necks, which felt good, then she lightly and briefly touched her thumb to my forehead. It sent the strangest sensation right through my body and TBH I haven't felt exactly "right" ever since. Was that supposed to happen?
