Not sure if i completed it or not but I'll post what happened.
After being in the dream for a while just following the story line I decided to try the basic task of the month to break something. So I was walking and I saw a huge table or piano made out of white blocks / bricks. I then activated my TK by saying something like "I have TK now so the should be easy" With the TK activated I held out my arms pretty wide and as i brought them back together quickly i crushed the front half of the piano and it turned to white rubble. Then i pulled the second half towards me and did the same thing. After that there was a tiny piece left and I realized something was coming for me so decided to mask myself by creating some white dust from the tiny piece. First i held out my hand in a fist and as I shouted"Dessimilate" or something like that, I flung my fingers open real fast. However nothing happened. I thought the dream / SubC didn't fully know how that command should work so i pictured it in my mind saying something about particles and then tried again. This time the piece exploded into white dust and rushed to conceal me as I fled.
