Quite a while ago I had a very strong dream, which is doubly unusual since I usually never remember my dreams. Anyhow, I was some manner of mid-grade officer and "doctor" on a sailing vessel, speaking French. Through the dream I basically watched usual life stuff, then came to a bit where I was attempting to explain something to who seemed to be a young native boy, and I said a few things in what I presume to be his language.
I hunted for that phrase a few days, turns out it was a loose Maori "like volcanos on skin". The boy had what appeared to be the beginnings of smallpox or some other terrible rash.
I could also talk about my reaction to the beginning sequence of Saving Private Ryan, but that could just also be psychological/etc. To boil that down I felt like I had died in my chair, if you had told me I was in wet mud up to my neck I'd have believed you. *Nothing* has ever hit me like that, and it does make me wonder.
