I Think My 15 Year Old Daughter Is A Medium 2

It has been a while since I've been here. My 16 year old daughter is a mental medium. She will get thoughts, words, and pictures in her mind that are not her own. School is very hard on her, and big groups of people are too. She is an Empath as well. Being a mother of a gifted child since the age of 2, as been very interesting to say the least. My mother passed 2 years ago from gallbladder cancer. I have seen my daughter take on the emotions of my mother, and others. The first time is saw this, it worried me. I took her to see another medium I know. She sat with Josie, and helped her see she is not alone. For many years I wondered why she would never stay the night at other peoples houses. Now I know why. I was afraid that if I didn't get her some help with this, I would end up with a poltergeist in my house. Just because she is a teen, and very emotional, and hormonal. What triggered this visit to another medium was she heard something out loud. She was very upset with this. It was something new she experienced. The medium I took her to, told her she has a male guide. When she graduated one gift he was showing her a new one. She said Josie was very powerful in her gift, and not to worry about letting the bad in, because there was a grandmother, and grandfather figure supporting her. They know she is gifted, and until she learns to control this better, they will protect her. Is this possible? My grandfather, my mother's father, passed a year before her. Does this happen? Do physics graduate, and progress in their abilities?
