DJ of lucid goals and how it goes

I'm sitting on a bed with IT and we are talking about something. The wall to my right is a glass wall and I see the people and town walking outside. I talk about the trachea and how I could strangle him with a throwing tool I have in my hand. He seems afraid. I Keep on pushing him mentally and he becomes unstable. He goes on a rampage and throws himself under the bed. I am scared because I don't know where he might show up. I get confidence because I was able to scare him earlier. I walk of the bed and prepare to face him, thinking that I can beat him. He jumps me from under the bed with long nails, sharp teeth and his arms stretched out against me. I become lucid and try to wake myself up. He starts to tickle me and it is terrible. I wake up.

Notes: In biology we talk about the different body parts that are active during respiration, the cell, digestion and circulation. I have a test on these subjects in two days and I am nervous and should have practiced more. In the dream I use biology as a weapon.
