From my understanding, there are 2 types of lucid dreams; High level and
low level. The low level is just that- a lower awareness during dreamtime that realises you're having a lucid dream but not aware enough to push the envelope and work things thru.

The high level is the higher awareness where you can control things in dream state.

At least that's how I understand it.

An example happened to me just last night when I went from low level to high level lucid dream.

I dreamed that I was an astronaut marooned on a planet with 5 others.
We were being chased by an invisible entity (No they weren't Apes) and we were running out of food. Anyway, the only one I recognised was John Astin- he played Gomez addams in The show "The Addams Family"

Anyway as the being approached I realised I was dreaming but I was scared and wanted the dream to end. SO I said to myself- "Addams home" and next thing I knew I was in the house of the "Addams Family" and from there I walked around the house and outside before waking up.

Now I kinda wish I hadn't chickened out of the first one.
