when she thought it over afterwards it occurred to her that she ought to have wondered at this, but at the time it all seemed quite natural
After reflecting on her experiences, Alice realized she should have found the situation strange or surprising. She recognized in hindsight that her reactions at the time seemed quite ordinary given the bizarre circumstances she was in. This shows how her perspective shifted once she had time to think about what happened.
During the events, everything appeared natural to Alice, despite the fantastical nature of Wonderland. Her initial lack of wonder indicates her immersion in the unusual world, which only later struck her as unusual when she thought it over. This contrast highlights her gradual awareness of the extraordinary environment around her.
