A childhood belief about ghosts

So I have these porcelain dolls that are always passed to the oldest daughter. When I was younger I always thought that they would come and kill me. These dolls had eyes that could blink and they were as tall as a normal 5-6 year old. That's what really creeped me out. When I would go to sleep I had to make sure all the doors in my bedroom were shut and all the lights in my room were on. Sometimes I would stay up really late and watch for a door to open. Sometimes floors would creek and the doors would be cracked open even though they we're enclosed before bed. Sometimes even the windows would be open the next morning. I also believed that if I didn't treat all my dolls with respect that they would kill me in my sleep. I would kiss and hug them all before I went to bed. In the mornings I would try and share my breakfast with them. I would try to feed them real food. I would tuck them in at night and treat them like a human being. I felt like if I didn't treat them right they would hurt me or attack me in my sleep. I'm 12 now and sometimes I still am paranoid but then again I do have ocd and anxiety so that might something to do with it.
