My understanding of phasing (what the 'updated' Monroe method is called) is not that you picture anything- it's that you let the pictures form and observe them impartially. There's a thread about it on the OBE research forums.
Its kinda hard to try to keep picturing images in your head and not fall a sleep i guess. practice makes perfect though so i still believe i can do it eventually.
Since you have over 20 posts, would you post a link to this?
Thanks, CF.
