Phish Sleep

I can't describe the feeling when I'm in my bed asleep and then
I wake up with a vision blurred, and all my efforts are deterred
To reconstruct this image lost

There're certain things my mind must do, and even though they're very few,
The image glistens like a gem. Repairing is not one of them.
So I'm awake, though in my mind, the image that's so unrefined
Is calling to me from the deep, and tempting me to fall asleep
