A repetitive image or idea in a text is a motif.

Explanation

A motif is an idea, element or aspect that is repeated at multiple times throughout a text to highlight the theme or message behind the text, the author is referring to.

An idea can be referred to as motif only if it used frequently.

The re-currency can also take place in various forms.

A motif provides the completed structural framework to form the theme.

Examples can be seen in Shakespeare's Romeo and Juliet- the phrase 'light and dark' is repeated in other forms like the night (moon) is no match for Juliet's beauty.

the narrator is saying that the old lady made her feel uncomfortable. you know this because they say "i found that rather irksome", "perhaps it was her being so upright and trim", and "i don't think it was that, because i thought that quaintly pleasant." hope this !
