Dream of naked

Dad tries to attack me but i defend myself by push kicking him away very softly, Then he talks about martial arts then tries to hit me again. I block every strike showing him that i could have hurt him with strike of my own but I don't hit him. then he grabs some plastic and says how about a knife attack at this stage im naked, im wondering why im naked, then he attacks me i block the knife attack but dad pulls me back grabs the knife in his other hand and pretends to stab me in the back. I mention that he stabbed me with the handle of the knife so then he turns it around and pretends to stab me with the point of the knife. Then I'm lying on a table and i see a big black and yellow spider on the beam above me. the spider connects his web to the beam then lowers himself down towards me, I try to move but i cant seem to, i call to my dad that there is a spider but he cant hear me. the spider lands on the table by my right arm pit then climbs up on me and just stands there looking at me.
