Has anyone else seen black, dead eyes in their N/P?

I have with all three... complete blackness, complete deadness, empty, sometimes extremely menacing, usually when their true self was showing. I don't mean just as a metaphor but really black and really dead and really menacing.

Some others have posted that they've seen this in their partners, I just wondered how many others may have done?

Apologies if this had already been discussed before.

Hugs
