Sure, it's possible आप will dream about someone आप like, but that doesn't mean everyone आप dream about is someone आप like. I've dreamt of people I dislike tremendously... and also of people I only met once.. या just saw and never met, etc.
Technically, our minds cannot make faces, so every face in our dreams is of someone we've seen before (in the streets for instance). I don't know if thats true, but I doubt dreaming about someone means आप like them. Maybe in a certain context it might. खोजिए for "dream dictionary".
