Is this abnormal in a child?

Starting when I was about 4 or 5, I would hear this voice in my head every now and then whom I just thought of as a creepy paedophile that wanted to abuse or kidnap me who would tell me to do things a certain way. For example, when the bathtub would start draining, I would get out really quickly because I imagined that he told me that if I didn't get out while it was draining, I would be eaten by snails that would quickly fill the bathtub. I knew that it wasn't real and that it was in my head, but I compulsively did these rituals occasionaly to satisfy it. It didn't interfere with my learning or behavior, and I knew it was in my head and probably grew out of it at about 8 or 9 and never had anything like it again. Would this be considered just normal anxiety and imagination for a child or a psychotic disorder? Also, if I had a disorder then does it mean I still have it? cause I don't hear voices and certainly never have since I was about 8 or 9. When I was little I told my mom about it but she just talked about it with me and asked me if anyone had ever abused me.
