could you type? maybe pen words on a pad? one word. let's start with one word. could you write it in a lucid dream? could you remember it when you woke?

could you write three words? could you write them and look at them, focusing on them remaining the same. ah! they change! inevitably, but if it's only three words, could you focus on putting them back to what they were? could you do it with a whole sentence?

can that part of our mind be strengthened with practice? that way, we'd have something tangible on awaking. "i thought of and wrote this sentence in a lucid dream..."
