Lucid Dreaming.
Last night, I had a very odd dream. I was kind of...awake inside the dream.

Recently, I've found that things pop into my head without me wanting them to and really confusing what I'm thinking of at the time. This annoys me.

So, in the dream, I walk into this wooden building and into this room. There's someone in a green T-shirt standing opposite me. It's me standing opposite me. I couldn't see the face, but it was my green shirt, and I just knew I was looking at myself.

And the other me said, "These things keep popping into your head because you're worried about them coming into your head. If you just stop worrying, and let them come, they'll go away. They keep coming in because you're always sort of thinking about them and sometimes your mental blocks fail." (That was the gist of it, anyway.)

I said, "Okay," and walked out of the building. And then I halfway woke up and realised that I had given myself a psychological analysis and a solution...in a dream.

This is very weird indeed. I suppose it supports the theory that dreams are a safe way of working out real-life problems.
