Cover art for Strange Deja Vu lyrics by Dream Theater

it's really really a cool song..! "i just can't help myself i'm feeling like i'm going out of my mind tears my soul into two i'm not the one i thought i always knew" it just representate my feelings sometimes when i felt so confuse about myself. listening this whole album makes me once again realize what a great band they are, what a great music they made..!

I think this part means the discovery of his existance as other person, not that he is confused about his present life. Something like "omg, I'm not just Nick, I am a spirit that is here and has been here before!
