Final Fantasy VIII Ending?

I assume there has to be a bit of fans out there of FF, I'm working on beating the game,a n the ending(Pretty much all of Disc 4, gets odd, I mean, besides the time Compression, can anyone help clear up this ending for me, story wise? I mean I got End Of Evangelion, but this isn't really clear at all. I assume someone believes the Squall is dead theory.
