This is below the 4 where I noticed that physical, palpable pain also accompanied the awareness.
It's about the same as the arthritis/gout sensation that I have most of the time.
Recently had a "dream visit" - very calm, very quiet, amazingly undramatic. This was on or around the beginning of October, synchronous to when we had learned that it was quite serious. When I noticed that there was a reality-disconnect, it was fine, I acknowledged that it was a dream and examined for anything significant, at which time actual message came through as words, "I'm still resting and recuperating, that last period was hard. I love you, and you need to take better care of yourself now, OK?"
At which point I woke up, feeling quite peaceful and even joyful.
And typing that out is actually harder than the realization that I was just dreaming.
