Yes, I have to agree with dreamcatcher - it is a 'simple' survival mechanism tampering some feelings (which are causing stress) and by that trying to reduce stress.
In extreme situations it is something wonderful - it flattens you feelings and hence makes you more aware (ie your rationality gets stronger - you can make a judged decision without the annoyance of fear or some other emotion) - if it stays permanent it develops into an illness - the symptom becomes the driver.
That's why I always tell to reverse the causality of things - by looking for emotions and doing the things you are avoiding DP/DR will gradually disappear.
Cheers!
