So... What if?

So, I day dream alot. A whole lot, it probably gets in the way of me doing the things I want sometimes because I'm just staring into space thinking of some stupid "What if" scenario (as in like an anime battle or something... because, you know, i'm a total dork like that).

Anyway, I like constructing battles in my head... like Lina Inverse VS Inuyasha or things like that.

Do you guys think that this sort of thinking/mind wandering is healthy? Yes? No? Let me know what you think either way!
