Well, with DEILD you technically wouldn’t be done dreaming. You’d be chaining one dream to another, so you’d write it down once you have completely finished. If you feel you can’t get back into a dream after a while, go ahead and stop to write and then go back.
As with WILD, the suggestion to not move doesn’t completely effect teh outcome, but it will make it much easier to slip back into a dream. For instance, if you have to swallow or you’re in a very uncomfortable position, it would probably be ok to move. You just don’t want to completely wake yourself up.
