Well I know it's about nam vets but for me the song has its own meaning back when it came out I had & was do a lot of hallucinogenic to the point of near madness and there was a few of us who would mess with each other while tripping if you have done it you know you can mess with peoples heads and we did like a psychic war of some kind and even if you won you may have lost and back then just like here and now its hard to explain it less you've been there just like any war so the bottom two comments are to the point as well.
