Great posts raspberry! Mantras are supposed to be short, and even "I am dreaming" is enough. You have to try different ones out

As for dream recall. It is something you will have to practice all the time. Sometimes it's good with a break, but other than that, try to record dreams every time you have them.

KNOW you will have a Lucid Dream. That is the most important thing while doing your mantra for MILD.

And if you intend on doing a WBTB, I recommend you sleep atleast a few hours more after you've gone back to sleep. But that's just me, I'm not sure if you need to. But I would say atleast 2 more hours. You shouldn't do this too often, and I only do it on weekends.

As for the doing part. Just do whatever you feel like, but like Raspberry said; Think about lucid dreaming as much as possible. I often read or watch some TV, and eat something.
