When your thoughts take you captive, there seems like no escape.  So many different ideas and not enough time to process them.  
You become prisoner
Everything that you once possessed is now captive
The governing authority in your mind is no longer your own
Your influences now lead you to darkness and isolation.  
The outside world now becomes the enemy
Anything that tries to permeate the inner chambers of the dark mind gets rejected
The war is completely internal and barely won by the strong  
The most interesting part is the turning point where the true nature of the mind embodies supernatural energy
