My mom saw a devil imitating me

Ok so I slept over at my mom's haunted house for the weekend about a year ago. I fell asleep on the couch in the small living room and my mom and my brother fell asleep in the recliners in the big living room. the big TV is right in front of them (the livings rooms are right next to eachother) my mom woke up in the middle of night cuz she claimed she heard me talking on the phone. she said I was right in front of her next to the TV, looking down, talking on her phone. then she said she heard me say (on the phone) "no grandma, mami's asleep right now. ok. I love you too. bye grandma". she thought I was talking to her mom so she went back to sleep. in the morning, I (in my actual body), awakened because my mom woke me up to ask me if I was talking to grandma in the middle of the night. I replied "no" and she had a weird look on her face that kinda scared me. like as if she had just saw a ghost. I asked her what happened cuz I knew something was wrong and she told me. my brother said he saw me talking on the phone too. my mom called my grandma to ask her if she was talking to me on the phone in the middle of the night and my grandma said "no". so we went over to her house later that night and my aunt was there too. so she told her what happened and my aunt said it was definitely a demon because "my" head was looking down. to this day I find it scary and wondering if it means something. was it imitating me because I was going to die? get hurt? what does that mean?
