Tell me why I can't remember

Tell me why I feel alone
Tell me what is it I'm missing
Tell me what I might have known

One night I dreamed of the Doctor
A time lord who left Gallifrey
A man with not one, but two hearts
He alone had escaped from the fray

Tell me why I can't remember
Tell me why I feel alone
Tell me what is it I'm missing
Tell me what I might have known

I dreamt of a strange blue police box
A box bigger on the inside
It travelled through many dimensions
I knew it as a safe place to hide

Tell me why I can't remember
Tell me why I feel alone
Tell me what is it I'm missing
Tell me what I might have known

I dreamt that we travelled together
This man called "the Doctor" and I
I dreamt that we fought against evil
We faced danger, but we didn't die

Tell me why I can't remember
Tell me why I feel alone
Tell me what is it I'm missing
Tell me what I might have known

Why is it I'm with him no longer?
What happened to cause us to part?
What happened to my lonely stranger?
Why did we separate, breaking his hearts?

Tell me why I can't remember
Tell me why I feel alone
Tell me what is it I'm missing
Tell me what I might have known

I dreamt I was the Doctor-Donna
A human and time lord combined
But now I am only a human
Why are we no longer entwined?

Tell me why I can't remember
Tell me why I feel alone
Tell me what is it I'm missing
Tell me what I might have known

It's lonely to just be a human
But worse to be just a Time Lord
When united, they both are amazing
It's a danger with a great reward

Tell me why I can't remember
Tell me why I feel alone
Tell me what is it I'm missing
Tell me what I might have known

The Doctor-Donna could not last forever
And so sadly he made me forget
He took away all of my freedom
Left me with longing and lots of regret

He is why I can't remember
Without him, I feel so alone
No more Doctor; part of me is missing
Our memories are what I had known

Tell me, oh my lonely Doctor
How are you, now that you're alone?
Separated, we feel something missing
Only in dreams are our travels made known
