I had a dream of a decomposing old lady in front of my window for two days in a row

In the first dream i wake up in my room and see my grandma looking out the window. I go up to her and see an old lady standing infront of the window, but she assures my its probably nothing. I don't remember what happened for the rest of the day except a lot of fighting between me, my grandma and my mother. 

In the second dream i wake up and go straight to the living room to have breakfast to try to ignore the window. After a couple of minutes my grandma comes in and we have a fight afterwhich i run into my room and go to the window but then i notice the old lady looks a little decomposed and then i wake up.

It was pretty creepy and i got scared so i just wanted to share this.
