#brain filter

When I have a bad flu or cold the membrane that keeps my subconscious out of my head seems to falter.

On top of a fever I get a  little glimpse of the madness going on under the cover. Thoughts going around and around, clashing on top of each other. I have not a chance to stop it

It gets so bad that sometimes I can’t sleep, which is very unusual for me.

That filter that is there most of the time and just let’s the important stuff through. I love that filter.

Everyone would, but many don’t seem to have it. As a result they suffer anxiety and other conditions. I wonder if anyone has even identified this filter function of the brain?
