A few questions:

1) How many hours do you sleep each night?
2) Do you wake up on your own, or use an alarm?
3) Do you practice any form of regular meditation?

It's hilarious that you write this.
Last night I began an attempt to reconnect to a lucid dream that I'd had a night previous which felt like the start of an adventure, and, hence, unresolved.

I sat in meditation, and brought myself back to the location in the dream where I'd woken up.
I felt myself move there, felt the veil shifting.
Came back.
The next attempt felt forced. I tried to keep a balance between holding it fixed in consciousness, and obsessing.
I felt like I accomplished a decent job of it.

The goal was to find a Machete, location unimportant, but to find a Machete, and bring it back to that spot.

I barely remember the dream to be honest.
I'm interested in doing further work... we'll see how it goes.
I'm using "Neptune" as a focus.

I wish I could give a better answer, but I'm having minimal luck as well.

As always, Lust for Result is one of the possible answers...

I've never managed to make it work.

However, I haven't tried real hard either. No journals, etc. My dreams have other magickal powers that I'd just rather not fuck with, if you know what I mean. Lucid dreaming, while interesting, isn't a big enough carrot to make me want to risk losing what I already have.
