Is it normal to make songs out of background noise?

Basically, I have this habit, I cant stop it and it really, really annoys me.

But anyway, I'll sit there and eat dinner with my girlfriend/friends/family and i hear the noises like forks scraping the plate, then the washing machine doing a cycle, then a dog barking, coughing, talking, the tv, the traffic, my heartbeat, peoples exhales, clocks ticking, the fire crackling, crunches of food, wrappers rustling, the wind blowing, the fan, the dog snorting (its a pug, its retarded, no literally its the weirdest dog)

I hear all of these sounds at once, no matter how quiet, and i make a little song out of them in my head, then listen to each one individually and ignore the others (All of this is against my will by the way) and it just keeps going and going, it feels like my heads gonna explode its not nice noises, they all irritate me.

Is this normal or am i a musical tard?
