Hey OP, I've had a similar experience and I have yet to come across anything explaining or describing it well (aside from texts dealing with Steiner's 'Lesser Guardian').

If you would, tell us more about the eyes. Do they move? Do they fade? Do they appear to be made of light? Most importantly: do the eyes remain equally visible when opening and closing your own eyes?

All the best, OP.

It's me OP again, no they don't move, they slowly fade away. I remember waking up and seeing Asuka's face instead of them. Don't know why.
They dissapear when I open my eyes, and they look like they're made out of very weak light.
