The series of events you have encountered is what is being referred to in paranormal circles as the "Black-Eyed Kids" or BEK, and it is a relative newcomer in the realm of paranormal experiences only being reported for the last 10-15 years. There are quite a few similar threads in all the reported accounts. The first and most obvious is the dark black eyes. you will find very few stories where the witness fails to point out that the black eyes or the fact that the eyes didn't have discernible parts (cornea's, pupils, etc). The second most common feature of these accounts is the "Plea" the BEK always have something that they need from the witness. a very common plea is to use the witnesses phone, or to be let in their home. they are always insistent on this request, after being told no, the BEK continue asking to be let in or to use the phone until a door is slammed in their face, but even then, they continue to knock for some time. Another common thread is the numbers. I have not found many cases where the BEKs did not appear in groups of two or three, which seems to intensify the frightening aspect of the whole experience. This Brings us to perhaps the most traumatizing aspect of witnessing the Black-Eyed Kids, The fear. Witnesses report being so struck by fear that they remain shaken up for quite a while. It's safe to say that if you experience the Black-Eyed Kids, chances are your not going to forget about it very soon.
