Overwrite

The mind rejects what it cannot conceive
So how am I to think of what went on?
I have my reason, so I must believe,
But underneath that everything is gone.
I look at facts, and know they must be true,
But nothing that I see can sink in deep.
It enters in my eyes and goes right through;
There's nothing given to me I can keep.
I know my mind still functions since I'm here
And able to construct these lines of verse
But everything I've heard has been wiped clear
For fear of hearing something somehow worse.
The ROM of me is sure it cannot be
Despite the RAM insisting that it see.
