How can I ever trust you? (Acheron) You can’t. But I have lived inside your memories for the last three years. I know the pain you hide. I know the pain I caused. If I stay here, I will go mad from the screams. If I return to the Vanishing Isle, I’ll languish there alone and in time I will probably learn to hate you all over again. I don’t want to hate you anymore, Acheron. You are a god who can control human fate. Is it not possible that there was a reason why we were joined together? Surely the Fates meant for us to be brothers. (Styxx)
There are other people that think that dreams actually do serve a purpose. But what that purpose is, we're not really sure. So some people believe that it actually does have some psychological representation of what's going on in the day, but there's no need to sit and really analyze it.
