meat cleaver-wielding octopi

This is the lucid dream I had last year.

In the dream, I was summoned to Zimbabwe, and was supposed to help the leader of that country, who was a king in my dream, with some unspecified problem.

I helped him out, but before returning home to Canada, I stole two igneous rocks of great significance to the people of that country. One rock was rust coloured, and the other was a pea-green shade. The green one was a boulder, and the red one was smaller.

Soon, I returned to Zimbabwe. The king was very disturbed that I had stolen the rocks. next thing I know, he summons his aides to deal with me. Before me appear three octopi, and they are wielding meat cleavers to try to kill me!

At this point, I am able to control the dream. So, I pull out a dagger, and kill the first octopus immediately. Somehow, the second one is defeated, but I cannot remember how. At this point, the dream became lucid. So, I consciously invisioned a wooden post, and made the third octopus hit his head on it, and black out.

That is when I woke up.

Any suggestions as to the meaning of the dream?
