Subconscious Writing

I have been sleeping for 5-6 hours then I started waking up in my sleep but having a hard time.

I dreamt I meet with Big Mama. There was some kind of competition here, something like a race. I think she was throwing things with such great power that it looks like she is throwing lightning bolts at us. I had to run and block the projectiles.

Then there was this scene where there is a game of dodging slow missiles. In another dream scene, there is this small cute dog following me.

Then in a final scene, I realized that I am dreaming so I took out my notepad and began recollecting these scenes that I have dreamed so I can note them down. Then I woke up, realizing that all that I have wrote down is gone! It's just a dream! So I have to remember the scenes again to record for real this time.

However, I realized that I cannot remember the dreams well. When I was writing in my notebook in the dream, I can remember all the dreams but as soon as I woke up, I immediately forgotten the details of my dreams. Is this how subconscious works? I can remember my dreams in my dream but I have difficulty after waking up. In an subconscious state, I can connect to my memory better than waking up. Is this how hypnosis works by connecting to your subconscious self to recall back forgotten memories?
