She can't determine how much time has passed when she becomes aware of herself. It's not really comparable to waking up because it's like she forgot she could but then suddenly was. But there are some things that the human mind is not meant to comprehend so she lets the thought float back into the depths of her conscious until she feels ready to tackle it.
She has a feeling that her situation just became more complicated than it has any right to be but she is also inexplicably excited. This is something new and unknown and she's always been a sucker for stories with adventure and a twist.
And dying is definitely adventure with a twist.
But then again, she's always been a little bit slow when it comes to accepting and understanding her own emotions, and a little bit too good at lying to herself.
She pushes that thought away. This is something she'd always known would happen eventually, and even if it happened a little earlier than expected, dying is the natural order of things and she isn't stupid enough to believe that denial of it will improve her situation.
Yet she isn't exactly sure where (or when or what) she is anymore. It's hard to tell if she's a now a being without a body or on track to another destination. Either way, she can still comprehend and analyze the situation, which is, frankly, beyond bizarre. Because she doesn't have neurons, or connections or a brain which would (should) allow her to think.
But then again, what about being dead and not just being dead, not just being gone and gone and gone forever, not just ashes in the wind and bones in the deep dark under, but being able to discuss and wonder and comprehend is normal or scientific.
In the end, she is obviously past the bounds of science and deep into the territory of magic and religion (because belief and doing the impossible have always seemed to go hand in hand in hand to her).
