Why have I had this one twice?

I've had this dream before, and it just leaves me confused when I wake up.

In it, I'm pretty sure I'm not me, and that I'm just in someone else's head for the ride.
This lady is married and has two babies (maybe three).  Her family is trying to run and escape the bad guys- cops/govt. people/the bad guys in movies who want to silence people who know things they shouldn't know.  It starts off as they're running and have the kids in a shopping cart, and they're going through a neighborhood where another woman is getting groceries out of her car and has her double stroller sitting in the driveway.  She calls my lady over and asks if she/I want to trade the shopping cart for the stroller, and swap some clothes as well (hat/scarf/coat) to help throw off the bad guys.  My lady agrees, straps the kids in (who are strangely silent the whole dream) and continues running off with the kids.  The husband is up ahead scouting to make sure they can get through the next area they're running through.

They enter this big barn-like structure (looks like a barn, but acts more like Main St. in a small town).  There are some of the bad guys with guns guarding stacks of hay on either side in the middle, but the husband thinks they can sneak past, especially since they traded the shopping cart for the stroller and have slightly changed their appearances.  So they calmly walk through and don't raise any suspicion.  The other end of the barn thing opens into a grocery store.

Now, for some reason, the grocery store is just crawling with bad guys.  The aisles are also really skinny, with piles of boxed food sitting in front of the shelves.  The husband is walking in front of the lady (who has now traded the stroller for a grocery cart so they can also steal groceries).  They get to the back left corner of the store (going down the dairy aisle), and in that corner is the door to the stock room, and a giant pile of Sprite and another giant pile of breakfast cereal.  There isn't anyone around, so the husband decides to re-stack it all to block off the door to the stock room.  He does that, and the lady takes the kids off toward the back right corner (passing the meat counter), tossing groceries in the cart as she sees things she wants.  The meat counter area kind of reminds me of the fight seen in the grocery store in Hot Fuzz, except no one is fighting, there's just a TON of bad guys.  The lady knows that if she can get past the bad guys in the meat counter area, then she can escape to freedom by going out the back right door that leads to a pedestrian highway kind of thing.  The bad guys notice her when she's almost there, and one of them shouts at the other ones and they start chasing her.  Then the husband shows up and I assume starts trying to fight them off.

I'm pretty sure the family makes it out of the grocery store ok though, and all the bad guys are just stuck at the door looking out all, "Darn it! We almost had them!"  But for some reason they can't leave the grocery store.  It's like the grocery store was the last civilized place, and now that the family is outside the bad guys are giving them up for dead.  Kind of like when the hyenas were chasing Simba away in Lion King.
