Is it normal to have a hyperfocus on people?

Well what you siad did sound compulsive and very obsessive behavoir , I have never heard of this in cases of OCD but yes I would assume this is most likely from your OCD becuase that is both Obsessive and Compulsive , and Disorders make it were we can not function properly in life so I would blame that on your OCD if you are infact OCD ...

i'm like that. sometimes i do stare at people and notice things about them more often than others would, and its embarrasing when i get caught :}

I don't have ocd but i do get what you're going at. I am super aware of everyone around me. When I'm doing tests and also, like ur example, when I'm driving. I can never completely focus on myself. it feels like i'm missing out on something. :( ugh when i see people who are distracted or preoccupied with what their doing and basically do whatever without having the people around them in mind. i wish i could be like that. my test scores would improve so much. but i just CANT. ..

I HAD ocd too but i can control myself now, its probably because of your ocd too ..

But I dont think u should consider it as normal, u should try to force yourself in any way to let your focus go off people and onto yourself or onto something that you feel is quite interesting at the moment...like daydream, or think about clothes or the person you have a crush on :)

Have u heard, to forget an ex-love you have to bring a new love in your heart....

Focus on some other more interesting thing...
hope this helps :) and Dont give up.

I have a problem with that too, but not to such an extreme. I look at everyone's face, and I try to remember them. i dont have ocd but I have add. I also only take pictures with faces in them.
