It is just a thought, 

It is darkness indeed, 

It feels like a never-ending night, 

And, you never feel asleep! 

It sparks a lightning, 

A sudden bright feeling, 

Then it is gone again, 

And, you feel lost again! 

It makes memories into demons, 

It makes dreams into ghosts, 

Too vague to remember, 

But too important to forget!
