Final answer:
The text suggests that the character may be interacting with ghosts due to several supernatural experiences and the belief in a haunted atmosphere.
Step-by-step explanation:
The question asks whether there are indications in a character's behavior that he may be involved with supernatural entities, particularly ghosts. From the excerpts provided, it appears the character exhibits behaviors and experiences that are often associated with ghostly encounters and haunted surroundings. Frequent references to a certain dread or unease attached to his residence and his peculiar conduct, such as a reluctance to leave his dwelling, strange responses to the environment, and the responses of other characters to possible supernatural occurrences, all suggest an underlying supernatural influence at play.
Furthermore, the other characters in the excerpts also experience or at least notice oddities regarding their environment, such as feelings of dread, objects that stir suspicions, and overall uneasiness that may point towards the existence of a haunted or oppressive atmosphere. It is clear that the actions and feelings of these characters are portrayed in such a way to give an impression of an underlying spectral presence or fear thereof.
