The state of extreme exhaustion when you do things without using your brains.
When it feels like your head is merely juggling with loads of thoughts and responsibilities but all of them appear to be useless and futile.
When your brain has a dull pain and it feels like someone is banging and striking it repeatedly yet you feel lost and disoriented from life.
When it seems like the world is revolving too fast and you’re attempting to concentrate and “catch the train/plane/bus” but nothing makes sense.
When the sound of every word you speak or hear seems to be muted and muffled.
When all this happens, dead beat is the condition for which sleep, laze and rest is the remedy.
