Daydreaming Gene

I was wondering… Is there such a gene called the Daydreaming Gene?

Could this gene be expressed when the brain is feeling bored of doing the same, monotonous thing again and again?

Or could it be that the gene is expressed to protect the brain from doing too much work?

Could this gene aid in reducing the rate of nervous breakdown during work overload?

Are there any factors involved in further enhancing or reducing the expression of this gene? Such as too much of listening stimulates the expression of daydreaming gene?

I wonder…

Just a crazy thought… might be true though… =P
