Sure, it's possible আপনি will dream about someone আপনি like, but that doesn't mean everyone আপনি dream about is someone আপনি like. I've dreamt of people I dislike tremendously... and also of people I only met once.. অথবা 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 আপনি like them. Maybe in a certain context it might. খুঁজুন for "dream dictionary".
