You're not weird, that's what every author in the world does. And if you're weird, then so are they!
You should write your daydreams down, if only for your own benefit. You find time to make drawings, so why not make time to write? And hey, you find lots of time to write things here
I say you should set aside some time to sit at the computer and type out one of your stories. And then another, and another. Then you should go back to the first one and expand on it, improve it.
Daydreaming like this has worked for JK Rowling, it's worked for Stephen King, it's worked for countless others. And who's to say you're not as good as they are?
