Dream of mother, apartment, bedroom, hands, eyes, father

I'm with my mother in my old apartment and we are having a chat in her bedroom. I go to the living which is dark except for a Christmas that is lit in the corner of the room. I sit in a comfy arm chair and in front of me is the corpse of my dead father lying as he did in his coffin but on a chaise lounge. I'm singing to him, a song I can't remember, and then I see the top half of his body slide off the chaise and onto the floor. I scream but I have no voice. My mother comes running in and she pushes me out of the living room and into the kitchen. She then goes back and repositions my father on the lounge. As she walks towards me I can see that my father is trying to move and flip flops on to his stomach sliding off the chaise and back onto the floor. We run into the living room and my mother tells me to grab a pen and to ram it under the backside of his skull to render him dead again. I do so, but it doesn't work. There's a table in the middle of the room that I run around to the other side of and there my father raises his upper body up like a walrus. My mother hands me a pair of huge scissors and tells me to cut off his head. I go to do just that but I stop when I saw the look on my father's face. He looks scared and confused. Very much lost. His eyes are black but that's because the eye caps they put in when he was being prepared for burial where dark. Part of it was popping out. I wake up yelling and was very scared to go back to sleep.
