I don't remember having imaginary friends but my aunt and grandma have always told me the story of how I was sitting upset one and time and they asked me what happened and I told them there was an older lady scolding me. From what I described to them they were convinced it was my deceased great grandma that had been giving me shit for something or other. Apparently she was a bit of a grouch and had died in that house. House was also super haunted in other ways from what they say.
