Of course, by materializing her memories, they are re-establishing or strengthening the neural pathways that would otherwise wither away with time. It's not necessarily grief-dependent memories when she "revisits" her loved ones but over time, the illusion becomes a weird trap that she would grow more aware of, creating an uncanny valley-like situation.

So not necessarily a "hell" but more like unneeded and distracting kitsch cluttering the shelves; turning your memories into cheap trinkets.
