yes people including me sometimes,thankyou for your post .

The principal causes of mindlessness are systematic lies and discounts which are characteristic of oppressive environments. We are all familiar with lies; a discount occurs when someone denies the validity of our experiences often by way of a lie. Systematic discounts and lies when we are alone, afraid, hungry or sick—in short, powerless--can combine to interfere with our thinking functions and can, if severe enough, lead to total mental breakdown.

When people's perceptions of mistreatment, deception, oppression or outright persecution, are ignored and squelched this most often leads to a confused state in which the person feels stupid and unable to think. Others can respond with large-scale obsessions which evolve their discounted perceptions into hyper-aware systems which become fantastic and unreal; at this point these fantasies are called "paranoid delusions."
