English; Symbols

In English, this time our task was to choose from three and I chose tunnel between both worlds the other mother's world and Coraline's world. This is a symbol to the well that we are introduced to around the start of the movie, as we come back to it around the end, to dispose of the key, as well as the other mother's hand. As some people believe that the well is the same portal on the other side that leads to the other mother's world, but it is down the well, some people have noticed the simulatíes between them too, the way they both seem never-ending. I am not the best at theories. As the deeper down the well you look you seem to notice it starts to look like the tunnel through the door to the other mother's world. I may be wrong, so you do not need to belive this at all. So I've found multiple images with the similarities. (This paragraph probably isn't related to the task I was meant to do, I was meant to write about symbols, but the is more like a similarity.)
