They do, and there's probably an underline to be drawn to the fact that Jack and others of her ilk use dreams to inflict terror on humans. But Murmur isn't wrong; this dream was more than just a dream - it was a memory of something traumatic, something that fundamentally changed Jack from human to monster. And she thought she'd been fine with that, embraced her newly-revealed true nature. But the fact that she's sitting in bed in tears speaks otherwise.

Jack doesn't expect the hug - she isn't used to being comforted. The gesture catches her so off guard that a fresh wave of tears bubbles up as she melts into the embrace. "Sorry," she mumbles, "sorry, I don't even know why I'm ... " and trails off, but she doesn't stop holding on to Murmur.
