I was thinking about death in a lucid dream, like it is some natural thing, (it kind of is... :\) and thought do you feel any fear, or is it all some "natural" feeling... Can't really explain it that well.
The only thing that was close to death in a dream for me was me riding abnormally fast down a hill in my bicycle, not being able to control it, and then waking up right before I crashed. I had no good or bad feelings about it.
EDIT: I mean feel any fear while you are going through your deadly scenario, like Sheath's tsunami scene.
