Dreams about bad parenting

I had them when I was pregnant, which I remember reading is very normal, but it had been a while until last night's very detailed dream: I left my two kids in the car in a crowded grocery store parking lot and went inside for quite a while. I had a few conversations with random strangers, took forever to choose a bunch of bananas and inexplicably filled a huge produce bag full of raspberries that I handpicked one-by-one from all the various boxes. When I got back out to the car, it had turned from day into night and two police cars with flashing lights were there. One policeman was lifting out my 6-year-old to put him in the squad car. I remember begging them not to charge me with child neglect, and then I woke up. I wonder what triggered this one. What about other moms? Do you have dreams like this?
