Frank, I believe you are correct. At least in my case.  When I was 10 my family moved to Alaska and we all lived in a tent on our remote homestead. One night I slept particularly warm and cozy in my old sleeping bag. Next morning Dad went to build a fire and make coffee and lo and behold a grizzly was curled up against my side of the tent!
He just groaned, got up, yawned and moseyed off into the woods.  Never saw him again, probably went to fish in the Copper River a couple miles off.
