I cannot find the meaning to this dream anywhere

I dreamt that it was halloween & I was running. I didn't know from what at the moment but I kept looking at the sky. When I got to a house that I felt was mine, I ran in and looked for a place to hide. It was empty but all the lights were on. I finally ran into my mom's room & locked the door. I hid besides the sofa to stay safe but that was right next to the door. I heard footsteps & then saw a shadow. Paper thin fingers appeared under the door and started groping my left side. Suddenly, I wasn't scared anymore and opened the door. The moment I saw the witch, I jumped on top of her & started sucking on her breast & then licked her vagina. This was all I remember but I don't understand why I dreamt it. If anyone may please help me, it'll be greatly appreciated.
