Despite her father being evil, the speaker still seems to miss him. But she doesn't say so in plain terms. She misses her supernatural father in supernatural ways – he's dead, so she figures the way to be with him is to become dead herself. Death and suicide are things that happen in the real world, but becoming dead so you can communicate with another dead person – that's supernatural. To top it off, her suicide attempt doesn't work, because her rescuers stuck her together with glue, which sounds kind of like Dr. Frankenstein's monster.
Now we get into the details of talking to the dead. But, surprisingly, the way to communicate with the dead is not overly supernatural, at least on the surface. It's just a telephone – but one that can connect our speaker to her dead father.
