When Annabelle rides her bike to the funeral home in the middle of the night she seems to be wearing flip-flops, and when she pulls up to the house it is actually clear that she has on flip-flops. But as she enters the house and walks around in the dark, it is very clear that she now is wearing fuzzy house slippers. After she is discovered by Elvis and gets ready to leave, as she walks out onto the porch, once again she is wearing the flip-flops.
When Annabelle is eating breakfast in the kitchen of the funeral home, her pink hoodie is zipped up. When she steps out onto the porch a few moments later to go home, the pink hoodie is now completely unzipped and fully open. Just a few seconds later, once Elvis decides to let Annabelle stay at the funeral home for a while, he shows her to an upstairs bedroom, and as she looks in the closet her pink hoodie is once again fully zipped up as it had been before she started to leave the funeral home.
When Anabelle locks Elvis out of the car she rolls down the window to talk to him. The window is rolled down farther in the interior shots than it is in the exterior shots.
When Annabelle is wandering around in the embalming room, she passes a glass cabinet door. Although she is alone, there are two people reflected in the glass; one is sitting, and one walks by.
