How should I interpret "it did not seem fantastic"?

I read a sentence in a story in my book which was:

The little girl, (not so little anymore; the bumps her feet made under the covers, were half way down the bed, their big double bed that they let her be in for naps and when she was sick) had at last arranged herself, and from the way her fat face deep in the pillow shone in the sunlight sifting through the drawn shades, it did not seem fantastic that some magic would occur, and she would take her nap like an infant of two.

Should I interpret the highlighted part as meaning that "the occurring of the magic had become so common that it did not seem fantastic anymore" or does it mean that "as she has grown older, the imaginary magic wouldn't happen and thus the fantasy is not worth having"? Although I strongly believe that the former should be right, seeing the premises I started having second thoughts?

Solution 1:

This is Fantastic in the earlier sense of like fantasy or unbelievable.

It did not seem unbelievable that some magic would occur.

Or It did not seem too far fetched that some magic would occur.
