Your imagination is getting the best of you. I've been there. I was a little concerned when he was approaching 'cause it was fast 'n' furious and I was a little afraid of being stepped on, but once I heard his pace slack off, then stop 4-5 feet away so I knew I wasn't going to be stepped on, my worry went away. I spent 45 minutes or so in my tent (tent? more like a bivy .. .90 inches long, 30 inches wide, about 16-18 inches tall) while the big guy messed with it apparently testing to see what I'd do. I don't know whether he left first or I fell asleep first.
It doesn't mean nothing can go wrong, but at some point, you have to realize life itself is a terminal illness, none of us survive it. Prepare for the worst, hope for the best, believe in yourself, in your gear, in your capacity to use it to rise to whatever comes.
