It was all Goosebumps for me, back in the day. Yet unfortunately, my mother seemed to believe that by the books (and I had quite a few) being in my room, well, she thought they were the cause of some nightmares I had, even if I hadn't been reading them. So she chucked them all out. No big loss for me because she tossed away her money. Whatever.
Anyway, my favorite of all the Goosebumps I had read was the one about the kid who didn't like to eat liver and had ghost dogs running around outside and then he turned into a ghost dog somehow and the ghost dog turned into him, and it liked liver. I forget what it's called but it freaked me out. Damn ghost dogs and their ghost dogish ways.
