I tried this about a week ago, and so far, every night, I've had lucid dreams, (even if they didn't last long) and even had more than one last night!

This is what I did:

Before I went to bed, I wrote a short story about someone's lucid experience, taking between half to one hour. I thought about the story a bit before I went to bed, before other thoughts took over. That night I found I was dreaming. The same happened the next few nights, and today I realised that I found out I was lucid the same way the MC (Main Character) found s/he was lucid! Last night I wrote that the MC had two FAs, and I had two FAs last night too! I find that I do the same thing the MC does, last night the MC didn't stabalise lucidity, and neither did I, so lucidity faded quickly.

Of course, if you're not a writer, you could try drawing, or something similar, but I don't know if that will work.

Please try this and let me know if this worked for you.
