<human>: Can you condense the text into a few key points?

Today I decided to mow the lawn because 1: It's a nice day and 2: I have eggs to hatch in Pokemon GO so bonus. I get everything set up on my phone so I start up the lawnmower and start. 10 minutes in, everything is fine. Another ten minutes, all good. But then I realize that there are a lot of flies around me. I don't think much of it and keep doing my thing. This is where I fuck up. As I'm mowing in a straight line I think "Hey, I want to listen to some music." So my stupid self decides to take a look at my phone while I'm mowing the lawn (which was dumb because I don't want to run over a rock or something and break the blades). Anyway I'm not looking where I'm going when the lawnmower makes a **BRRRRR** kind of sound. Obviously I turn off the lawnmower and think maybe I ran over a stick or a rock or something. But then it started to smell. *badly*. Like, *really* *badly*. Then I remembered the flies and now I know something had died and I just ran over it. The smell is really bad at this point but I had to investigate so first I move the mower. Blood all over the ground. That's not that bad, right? Wrong. Then I had the sense to open the bag at the end of the lawnmower. I was not prepared, Reddit. There was blood, bone, flesh, hair, and more blood everywhere as well as grass. I gagged it was so disgusting. I had to walk away to collect myself, looked again, and then went inside. Now I'm inside trying to will myself to clean out that bag^killme.
<bot>: Ran over a dead rat with a lawnmower and now there's mutilated rat inside of my lawnmower.
