Porcupine Tree – Dislocated Day

Wilson's is the voice on the phone. The song itself seems to act as the voice mail or something. Before the song begins, we hear the phone ringing from the caller's point of view, then the song, then Wilson hanging up after leaving a message. It is also possible that the song is an outgoing message that the caller (Wilson) hears before leaving a message (you know how many people have music as their outgoing messages???) The person that he is calling is not answering...so he is dislocated.
...and then we hear the message that Wilson leaves...One thing that I think I deciphered from it is something along the lines of "...I think it would be an interesting ending...Let me know what you think..." Before that I believe I hear the word "guitar" being spoken in reference to the ending of the song (the song ends with guitar alone). It is Wilson calling a band mate or studio engineer and leaving a message. The message involves an idea for a song and Wilson is calling someone (Maybe Richard) in order to get an opinion of his idea. The "interesting ending" is the voice mail suggesting that the ending of the song should be a voice mail suggesting an interesting ending. ;-P
