Waldeinsamkeit (German): the feeling of being alone in the woods.
I spend a fair bit of time 'alone in the woods' (well, with canine company but that's different). So what's that feel like? I'm not sure,I usually don't stop to think about it. There's something there I keep trying to glimpse or feel, I suppose, but I don't have words for it. Then again I don't speak German, so I guess it's okay.
