Longinus

That is pretty rough... Undertow is dealing with, in my opinion problems we all face and all aware of with other people surface problems I suppose. Ænima is dealing with psychology of our own minds through the ideas of mainly Carl Jung,Sigmund Frued, and Tool, though there may be more I think these are the three most obvious influences. Lateralus is dealing with self, though it is based on communication I think it is the communication between a person to themselves. These are all just my thoughts though, and I am most likely only right in my own mind.
