Hmm.

At first glance, the thought of making up your dreams seems unhelpful, if not counterproductive. But then, a couple of glances later, it sort of makes sense.

After all, dreams are all about imagination; a little conscious imagining couldn't hurt. Also, writing things down has a lasting impact, in terms of memory, so by writing down imagined dreams -- and/or hoped-for dreams -- you might be helping create some expectations and day residue for future dreams.

So this may be a good idea after all. Just be sure that you indicate in your journal which dreams are fakes and which are real (when they are finally recalled)... unless of course you don't care, because either way the story was yours...

Here's another odd thought: Because (non-lucid) dreams exist as memories only, and fleeting ones at that, I often wonder how much of what we recall and record of our fading dreams actually happened, and how much we add to the record, either because we're trying to fill in blanks or are inadvertantly embellishing the memory as we rerun it in our heads... Who knows? We might all be recording fake dreams already, at least partially!
