Screaming or howling

Setting: my suburban area, grandparent's house, all houses in neighborhood are extremely close together. Day time Characters: Older Sister(Tiana), Little brother(Jeremy), Mother Experience: <PERSON>, <PERSON>, and I are relaxing in my room upstairs. We are all discussing mom's behavior lately. Not only has she been acting strange, but she seems to be very ill but refuses to lie down. One other thing that my siblings and I noticed about her is that she constantly goes down to the basement throughout the day with a plate of food...almost as if there is something down there she is feeding. Mom enters the room, her face is extremely pale and there are heavy sags under her eyes. She says to us, "Lunch is *cough cough*...ready whenever you guys want it...just come downstairs..." We all look at her in worry. She leaves the room and heads back to the kitchen downstairs. I follow her. I needed to know what was going on, as I head down the stairs, I get a strange feeling that something is watching me. In the kitchen. Mom is standing by the kitchen table, her back is facing me. I ask her, "Mom, are you ok? You have been acting strange lately and we are concerned about your health too." At that moment, a low growl echoes from the staircase leading to the basement. My heart begins to race, and my mother slowly turns her head around to look at me. However, her eyes are completely black and she says mutters words I cannot understand. I can only stare on in horror as my mom's body drops dead in front of me. I begin to rush toward her to check her out but the moment she hit the floor, the basement door swings open and my mother's body is dragged across the floor and down the stairs with tremendous force by an unseen entity. I knew we were in trouble, wasting no time I bound up the stairs and back to the room. "<PERSON>, climb out the window now!" I yell. Without hesitation I open the window to help my little brother out first. As I am holding his hand and lowering him out onto another house's roof top, my room door is blown away and in flies the most terrifying and unexpected figure, my mother...except, it was not really her, whatever entity it was that dragged her into the basement has taken over her body, her skin is gray and muggy and her eyes are as black as death. She raises her hand and points at my sister. My sister screams but it is cut short because her body begins to expand until she explodes from the pressure... "<PERSON>!!" I yell, but my attention then snaps to my little brother who is hanging from my hand, his body too begins to expand...I close my eyes to avoid seeing another death, but the vision still pops up in my head as he explodes..left with nothing, I dash out of the window, promising myself to mourn their death's at a better time...as I am running and jumping from rooftop to rooftop I can hear the entity behind me flying above and swooping down at me, I duck and dodge and search for a safe place to get away but I see none, nowhere to escape...(wake)
