weirdest dream ever....any ideas?

So I've been trying to break my bad habit of biting my nails so I've been getting shellac put on them and I haven't bitten them for a good month now I'd say. For the past week now though I've been having the weirdest dream ever every night. It's always about my finger nail polish falling off  and my nails aren't done anymore. Wtf right? Does anyone have any idea (specifically anyone who knows about dream analysis) as to why this dream keeps happening and what it could mean? Or is it just random as hell?? Lol
