I have a theory on the Shawshank Redemption's ending

That there's a moment during Red's parole hearing where red disassociates, and everything from getting approved, being out in the world, finding the treasure, and going to Mexico was all a fantasy, it's all in Red's mind. For two reasons, the first is that the further we get away from the stamp the more fantasy like or dreamlike it becomes. Colors get brighter, the tone shifts and at the very end it absolutely feels and looks like a dream. And the second is what Andy said about how he dealt with being in solitary confinement, that he just escaped into his mind and listened to music. I think Red did that instead of dealing with the crushing reality that he's never leaving. BUT, that just how I saw the ending. The director even said himself that they really do meet in the end.
