Polar Bear

I'm in this totally white environment, like a detergent commercial. It's not cold or snowy, just white. I'm walking along a slightly bendy path when I spot a polar bear about 100 yards away and he spots me. I start running away. The pb gives chase. Just when he gets to me, he leaps up into the air to pounce on me. I turn to face him, reaching my hands up in the air hoping to catch him and pull some kind of judo move and throw him over my head. The dream ends.
