a blank - When the page is so blank it's like the universe just erased

When the page is so blank it's like the universe just erased everything and left you with nothing but silence and a very confused pencil.

I opened my notebook and it was blank like my brain after a 10-hour math test.

I tried to write something and the page just stared back at me like it was judging me.

I turned on my computer and the screen was blank like my brain after a 10-hour math test.
