It just happened 10 minutes ago, so, no, it hasn't sunk in yet.

Dad, thanks to TV, I can't remember what happened 8 minutes ago. No, really, it's a serious problem. Ha, ha, ha! What're we laughing about?

It still has not sunk in yet.

It's like it's not real. It really hasn't sunk in yet. It comes and goes.

I'm still waiting to wake up, it hasn't sunk in yet.

It feels unbelievable. It still hasn't sunk in yet.
