The only little thing (and it is NOTHING like your two experiences) I have had was when on Honeymoon, my husband and I went out one night, when we came back I slipped over and banged my head very hard on the tiled floor. I remember thinking "I am going to die". However, in the next minute I awoke, it was morning and I was in bed.
My husband said I had not slipped over and neither had he put me to bed.
Your two experiences were extremely interesting (you got any more?)
