The episode specifically states that this is the case. She’d been chatting with her elderly mentor about old friends dying off and how it’s like they never existed, and she’d been mulling this over at the point at which she was sucked into the bubble causing it to manifest.
It’s always seemed stupid and jarring to me, but I imagine they added it in to help people understand the concept.
Her subconscious didn’t make things disappear, the collapsing bubble did. She bares no blame for this event.
