Very interesting, and your experience of being "stabbed" in the ribs is similar to something I read last night:
The Old Hag
So as indicated I was asleep, peacefully snoozing away when suddenly my restful sleep was torn asunder by a merciless kick to the ribs (at the midway point between elbow and shoulder - a little closer to the elbow...) This was a potentially life threatening blow that hurt for weeks afterwards - it was as if I had received a thrust from a cosmic sword! Of course I [awoke from] this and stared around the room only to immediately realize that I was paralyzed - encased in "psychic cement." I could move my head [from] side to side and up and down but no movement below the neck line. I thought [to myself]: "Huh? What am I dying?"
I had just went to sleep a few hours ago and now what - heinous pain in the ribs and no movement below the neckline? What have I done to myself? I looked to my immediate left and viewed my red LED digital clock: it read 3:15 a.m. but there was something sinister about that readout!
