Why do i keep having dreams of a Glock 19?

I own a Glock 17, and a Glock 26 as my back up piece. idk why but for the past 2 weeks i have been using a Glock 19 in my dreams almost every time i dream. is that a sign for me to get it? i dont really see a use for it, seeing as my G17 holds 2 more rounds and i can conceal it easily.
