Dreams with very clear faces

[Sanity Claws]

Within the past month or so, I've had dreams where I see the faces of people I don't know. I have always had dreams with characters in them but for me the characters were people I knew or kind of faceless generic type people. The change is that I now clearly see faces of unknown people.
Do you normally have dreams populated with real looking people whom you don't know? Is this significant?
