Is it normal to imagine a family based on a book you like?

So last summer I read Alice in Wonderland and Through the Looking Glass and I had an interesting thought: what if, when I get older, I had a white cat named Snowdrop and a black cat named Dinah, and I had a daughter named Alice (it would be a lucky coincidence if she ended up with blonde hair and blue eyes and a British accent, perhaps I should marry a girl with those characteristics). In all honesty I'm not much of a cat person, and being a guy I think it would be a real challenge trying to raise a girl (no offense).
