Eli5: Why do alcohol make us change preferences?

I totally get beer goggles or being more extroverted when drunk, lower inhibitions, worse judgement and all that.

But how does it change why we want to do. If I'm sober i actively dislike the dancefloor, I don't know what to do, and i don't see the point? If I'm already drunk though, i absolutely love it?

Same thing with cigarettes, i have friends you couldn't pay to smoke while sober. Or making plans you would never ever make while sober?

It lowers your inhibitions and risk assessment skills. You don't dance in public and your friends don't smoke because your sober brains decided it is dangerous and they don't want to. Drunk brain doesn't give a fuck. 

You kinda answered your own question. Your preference is because of inhibition.
