Sunday night (or rather, Monday morning), I was awoken from a dead sleep by the sound of my husband breathing rather heavily. Trying to figure out what was going on, I leaned over the pillow that had made its way between us, and saw that he was lying on his back, and beginning to hyperventilate.
My first thought was "he must be having a sex dream!" but as his breathing quickened and his face began to reflect panic, I realized that he was actually having a nightmare.
