K9 (he's a robot dog from the year 5000, in case you were wondering) has been running regular scans of the fog since it arrived and some of those affected by it.
I'm sure most of you are aware by now that the voices are not externally audible but are a result of the 'fog' affecting our brain waves.
I'm not saying they're not real, they are
very real just not an actual vocalised voice. The more time you spend in the fog - combined with how advanced your senses are - the quicker it affects you. Telepaths and empaths and those receptive, are getting more because we're picking up on all the affected brain-waves and what is going on inside their heads.
The way it's progressing and from K9's readings, it may even affect other portions of the brain, moving on to the other senses. Fear and aggression triggers in the affected are lighting up like a Christmas tree. Bit early for Christmas but it makes sense. Sort of.
The 'fog' is getting thicker and almost tangible in places. It could be possible that it's 'feeding' on the fear, aggression and paranoia from affected brains which is making it stronger. Allowing it to take on an actual physical form. Wouldn't be the first time. Minds of people are powerful things and lesser entities have been manifested from them before.
All those that can, it would be best to stay inside
although I don't think it will be long before even that's not safe or head through one of the doors. Especially if you have children to worry about. If you can convince someone affected by it to go through, that would be brilliant. I think going through the doors will cut off whatever link this 'fog' has established and hopefully help them.
