I guess nothing is worse than a semi lucid dream when u know ur dreaming but u don't do anything
I once had a water bending dream.
I shaped water using my hands, I knew I was dreaming but I didn do what I wanted to do.
I lost my lucidity and I found myself doing stupid things
Then I gained my lucidity again bcz I was sick and woke up several times and slept back during this
Made a castle of ice that was my purpose it was so real. Every detail looked exactly as I expected and I could see my reflection
I looked fatter and thinner
I made a snowman and crystals near the entrance of it.
Unfortunately mom woke me up and didn let me enjoy my dream in which I turned lucid.
