Dream of

I dreamt that i went back to my family house were i grew up my mum and dad was at the weekend as i walked up the path. My mum has been dead for 29 years, she was wearing red cords and a blue short sleeve shirt an outfit i recall from when she was alive. When i entered the house i went in living room my mum was sat down on a chair and she started to look really unwell as if she was decomposing infront of me i asked if she was ok knowing she was not. She said she said she was fine and got up and started to pace infront of me, i felt scared and i kept saying mum you are dead rest in peace over and over again. she then walked out of the door and i felt petrified
