What about her upstairs neighbor?

He as well is another of these troubled individuals, so this is an iconic representation of her plight, that she is sandwiched between two potential mass killers, at least at the extremes of possibility. Whether either will reach that dubious status is uncertain at this point, but things are bad enough in their arbitrary and mean-spirited acts of hostility and vengeance that are uncalled for and wildly excessive, many times, only in reaction to perceived slights when nothing at all has been done to them to engender a backlash. This shows the futility of trying to be safe totally. When in range of such individuals, they will seek you out and make you a target on their own. The only defense is to escape from their environment, forcing them to find other victims. The healing outreach is the only true way to eventually contain things, but that will take time. You are up against a very strong concerted effort backed by the entirety of the Extraterrestrial Alliance and the spirit meddler community both, so this is no small challenge. They are among the high‑level perpetrators you are facing and must contend with to save humanity.
