The mist confused and teased him, making things seem unreal and unstable which would make him more scared as anything could be near him but he cant see it. Above all, it was the suddenness of it that had so unnerved and disorientated me the words unnerved and disorientated show that Kipps is not sure of himself like before, and is getting more panicked. He says the walk back was a nightmare, which is ironic as the scariest part hasnt happened yet, but shows that Kipps thinks that this is as bad as it can get and nothing worse is going to happen, which makes him even more scared when it does. The sense of hearing is also used to create tension and suspense. I heard the sound that lifted my heart, this false hope makes the reader feel safe for a moment, which contrasts to the horror that Kipps feels next.
He realised that the mist was playing tricks with sound as well as sight, which means he cant trust what he is hearing or seeing and gives a sense of insecurity and vulnerability. Hill describes Arthur as feeling chilled and horrified. She has chosen these verbs to emphasise the feeling of terror that Arthur feels. Both words are in the lexical field of ghost story, which creates a scary and creepy atmosphere. The effect of these verbs on the reader is that they will understand how Kipps is feeling because they will also feel these emotions. Hill uses first person narrative which makes the experience feel more personal and real, and helps the reader to empathise with Kipps and feel the terror the he is feeling.
