Is it normal that i am extremely aware?

So, lately a few things have been going on. In the past three months I have for some reason become hyper aware of everything going on around me. I can fully understand and hear conversations going on across the room from me, my brain gathers information and files it quickly, I seem to know everything about everyone because my brain is keeping tabs. It pays attention to every move someone makes, every subtle gesture. I haven’t always been this way. This recent mental-sharpness is very abnormal, considering how much I pick up in a social situation vs. others. It’s not an age thing, because even people older than me (at least that I have met) aren’t this aware all the time, and all of this sorta just came out of the blue.
