Yesterday night, as I was trying to WILD, I noticed something strange happening to me:

I was lying there, counting, focusing my mind and trying to relax when all of a sudden my body relaxed all by itself; my breathing intensified and quickened, and I was quite conscious of this.

Could anyone tell me whether this marks a certain sleep stage (and if so, which one it is...)? (Itll be useful when keeping track of progress during WILD).
