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?)
A few weeks ago I was walking down a quiet street on my way to the shops. I was about to cross the road and noticed a car coming so I waited. It didnt pass me it pulled up at the curb, the owner switched the engine off and got out. I looked the other way before crossing and when I looked back no car!
My most scary experience is getting up, having a shower, putting gel on my hair, drying it with the hair dryer and when I went to unplug the thing not only wasnt it plugged in I realised I didnt actually plug it in either.
I have several of these incidents and they always happen when I've been a little tranced at the same time.
