I do not have eyes but I once could see. I used to have thoughts but now I’m empty. What am I?

Question

I talk, but I do not speak my mind
I hear words, but I do not listen to thoughts
When I wake, all see me
When I sleep, all hear me
Many heads are on my shoulders
Many hands are at my feet
The strongest steel cannot break my visage
But the softest whisper can destroy me
The quietest whimper can be heard.

SKULL is the answer.
