Blind is the first single by American nu-metal band Korn. It appears on their [self-titled debut album]. 

 A reference to Jonathan's drug use during his early years.  

 "Another place I find to escape the pain inside"  

 The drugs controlled his life. They provided an escape from the pain he endured as a young adult, and he couldn't see any future direction for himself.  

 "see through the grey that clouds my mind"  

 He wants to escape the confusion in his mind but his self esteem is so low that he is not confident enough to make change for himself. He wants to leave the world and start again but he doesn't know how, so he uses drugs to distort reality.
