Easy visualization exercise for MILD

In MILD and Intention Technique, as described in EWOLD, Laberge suggests visualizing yourself becoming lucid in the previous dream.
The problem, of course, is that sometimes recall is poor or inexistent. When this happens what to do ?

Does it really have to be the previous dream ? Can we use any other previous non lucid ?

But, for what this thread is about : can we use some waking life memory ? For instance, the memory of the day ?

It is still fresh in our minds, and we don´t need the mental burden of creating and visualizing a whole new plot. We can just incorporate some fantasy elements.

For example, i remember today i was waiting for the bus and then i remember arriving home, meeting an old friend and so on.
So, when practicing MILD i can visualize myself becoming lucid at the bus stop after spotting some oddity and then visualizing and making small changes to my memory blueprint, but without changing the main story of the day.

Just an idea to keep MILD rolling when conditions are tough :)

Sometimes I do something similar to this if there is an event that occurs during the day that would have been an adequate dream sign but I didn't pick up on it at the time. I'll visualize the encounter again but then after it happens I ask myself if I'm dreaming instead of doing whatever else I had done. Obviously it probably isn't as effective as if I had done it right then but I figure it's better than nothing and will help me get faster at picking up on them. I assume as long as you're practicing picking up on dream signs and visualizing well enough it doesn't matter if you use recent dreams or old ones, or even waking memories. But I'm not experienced enough to say for sure, just seems plausible to me :P

I have asked myself this question. I assumed it was something to do with the brain still consolidating the dream events when you wake which makes for a good time to add a visualisation?
