I'm Thinking of Ending Things discussion

Near the beginning, the narrator mentions that someone had called her and it was a wrong number. Later she receives more calls, and goes on:

"I checked my missed-calls list and saw it was the same number as the wrong number from the day before. That was weird. Why would he call me back? But what was really weird, and inexplicable - and this still makes me upset - was that the calls had come from my own number."

How was she receiving calls from 'the same number as the wrong number the day before' AND from her own number?

Confused.

First of all,this book is well written and it is a psychological thriller.Its so difficult to say anything about this book without giving anything away. My advice..read it first:)

she says it was the "wrong number" cause she assumes it was someone making a mistake and dialing her number instead of someone elses. which is why its weird that this "wrong number" called her back... and that its somehow coming from her own cellphone

She said it was the wrong number because she didn't want to tell Jake that it was this strange, unexplainable thing happening. She covered up the strangeness of the calls coming from her own number by just lying and saying it was a mistake or a friend (in the movie)
