2nd Holly Dream

So I had a 2nd dream about Holly. This time I open the front door and Holly races out to where the railroad tracks are straight into a train that is going by (apparently I have railroad tracks right outside the front of my house in this dream). I hear only 1 yelp and she is down. When I go to investigate, Tammy is calmly scooping her up (Holly looks like flat beaver roadkill) using a large shovel and putting her into a garbage bag (no tears of loss). I am mortified in the dream, because I thought Tammy was scared of spiders, and here she is taking care of this scene? Then I wake up. I try to recall: Have I watched a horror/thriller movie lately? Nope.
