Literature is to be enjoyed, not always to be studied. Stories such as Alice's are a pleasure to read for their peculiar yet still unique demonstration. I remember reading it for the first time and just enjoying imagining the incidents and creating wonderland as I have interpreted it in my head. You might be able to interpret a meaning to the story if you revisit it again, but it's totally fine if you don't reach a conclusion. Just read for joy when you need or want to. It's always a good boost for imagination ☁️
