mind dead

1) when you don't want to go to sleep but aren't awake enough to do something productive.

2) similar to being a vegetable, except you are locked away in the awesomeness of your currently being binge watched TV show.
3) when you are so pissed off at/about something/someone that you are unresponsive.

1) Josephine was laying on the couch doing nothing because she was mind dead.
2) Alexi was on the couch watching a TV show on her tablet in a state of mind deadness.
3) Jonah killed Tina's cat and Tina was so mad that she was mind dead.
