This is quite a short, proggy blues song with a flute solo. Thoughts would be appreciated

There was a time when I whiled away the hours
lost in a deep dark hole
kept awake by crackling wires
Silently I raged

there's a lake inside my head
but no fish are biting today
they've been scared off by the smoke and haze
of heavy industry

these experiences have served me well
but i've got to break the spell
go walking on a dry river bed
find somewhere new to lie my head

In the meantime it helps me to know
Time is just another illusion
And lunchtime and teatime are doubly so
You reap what you sow
I've read this a couple of times and it's really good.

The idea of not been able to sleep because your minds empty is a good well used context.

The only issue I'd raise is that I had to read it over a couple of times to click onto what was been said, and in a song if your too descriptive you can sometimes lose the audience as they soon start to wonder what your talking about.

Just a couple of more literal lines to steer this and it would be a great song (IMO)
