Blue October - Into the Ocean Lyrics Meaning

I think there are many more layers to this song than most have touched on in their ideas of how this song can be interpreted.

To start with, I think the character in the song didn't just simply allude to him jumping overboard to commit suicide, but also that he jumped overboard into the relationship in the first place, ie,

Now waking to the sun
I calculate what I had done
Like jumping from the bow (yeah)
Just to prove I knew how (yeah)

The speaker jumped into the relationship before he was truly ready and was over his head, just as he found himself when he jumped overboard. It is this relationship he is seen fighting against in the video, where it is represented by a "Moby Dick" type whale - it is something he wants desperately, but can't seem to capture, and perhaps will be destroyed by.

The voice singing "Into the Ocean, end it all", represented in the video by three ghastly-looking ballet dancers, is clearly an allusion to the Sirens in Greek Mythology, who would lure sailors to their deaths. They might also represent the Furies or even the Fates, all female characters that had the ability to control the course of men's lives, and even drive them to their deaths.

This is just my interpretation of the song. I find it to be one of the most intriguing songs to be written in a long time, and as a previous writer stated, a good song can be interpreted on many levels, and this song indeed lends to varied interpretations.
