Fiction - Careful [tekst, tłumaczenie i interpretacja piosenki]

Where is that hand?
The one that kept you moving along
Like a rational headed man
With a rational heart
And what’s this?
It’s like a can of heat
And if it blows up it will take you with it
And if it goes under it will drag you down
But if you hold it tight
It could make you happy
And all the cars would care about you
But you are not mechanical
And all the trees would laugh about it
But you are not invisible
Carefully dragging your feet
Where is that thought?
That perennial secret of yours
Well you’re keeping it hidden of course
But it’s never delivered
But what’s this?
It’s like a can of heat
And if it blows up it will take you with it
And if it goes under it’ll drag you down
But if you hold it tight
It could make you happy
And all the cars would care about you
But you are not mechanical
And all the trees would laugh about it
But you are not invisible
Carefully dragging your feet
Careful cares for you
When you reach the edge
You may not fall asleep
