I used to have a recurring dream as a child. I had a bunk bed in my room which was often pulled slightly away from the wall, and in these dreams one of the dolls my mom kept in her display cabinet would find its way into my bedroom, possessed, and attempt to kill me. The dreams were slightly more advanced than that—the doll would never speak, it was omnipresent at times, it could teleport, and it had semi-psychic powers. But this covers the basics.
I dreamt that again, but this time I was grown. I outsmarted the doll, baiting it out from the crevice between my bed and the wall. The doll looked to me and revealed to me that it had only come to warn me of something: A much more powerful enemy from my childhood would be returning.
Outside my father was connecting the three RVs owned by my family together in some attempt to create an exotic super-weapon. The doll escaped out to the campers and attempts to rip up the poor cable-work my dad had haphazardly wired together. We managed to jump it and tie it down, beginning a exorcism on the spirit which had possessed the doll.
It tugged and pulled at its cord restraints, with such force that at times it shook the campers it was attached to. But it was no use, we had it captured. We exorcised the spirit.
