I discovered that sleep tends to mitigate the 'stress' that one gets by trying to deal with logical problems like work related tasks and general daily life tasks. Does sleep do this by removing the tendency for human to think logically as when we see dreams, they are highly illogical such as "fork made with orange peels!"
Is it the fact that in sleep the parts associated with stress i.e. logical reasoning part of the brain is being shutoff that results in weird dream contents?
