Woke up to some issues this morning

I had no power in my room. The circuit breaker broke for no reason. Don't know what happened. I know it wasn't the skimmer this time because nothing was wet and it was working fine.
What do you guys think could of happened

 

did anyone get up before you this morning and use a blow dryer on the same cuircut?.. thats about the only thing that blows circuit breakers in my experience(unless you have an integrated breaker in your bathroom). other than something with your tank equipment anyway. and is everything working fine since you have reset them?

 

The circuit braker in the bathroom controls all of the upstairs, I'm the only one up here so nobody used a blow dryer or anything. And all the equipment started up fine right after I reset it, and everything was fine when I went to bef

 

so my dad is thinking of possibly putting an alarm on the cirucit braker so i know when it goes off, i'm usually a light sleeper so i know if my skimmer has turned off or not, but i must of been knocked out cold last night and didn't notice anything
