I am writing this for a friend. She turned thirteen recently and we believe she may have developed clairvoyance. She says she has a gut feeling before things happen. For example we were playing a online pong game. We both had one cup left, and I jokingly said this is getting intense. She immediately won, and told me she had a gut feeling. Another time, in school, the teacher chose her to read what she wrote first. My friend didn't want to read, but once again she had that feeling. She recently had a dream that a family member had died, and that person went to the hospital soon after. (The person made out ok). I was testing her by having her guess random letters. She guessed L, but then directly when she said that she knew it was R (the right answer). She shows a lot of signs of clairvoyance. The strangest incident was when she was home alone, she said she felt someone calmly watching her. Her mom came home and told her that a relative had died, around the same time she got the feeling. She also once said after that she kept seeing dark shadows in her house. She would love to have someone confirm this, and if anyone can help us hone her gift that would be great!
There's always a chance she does have some abilities. I recommend writing all these down when they happen, and include details like when, where, what the thought was, any feelings at that moment. Recognizing those things can help her identity the gut feeling more specifically and may help her have more control of it.
ALlso, writing these down helps give her confidence and help keep if when she's feeling doubt in her ability.
I have times where I doubt I have any ability at all but I remind myself of the things that have happened, or what I knew was coming, what I've accomplished through my ability. There are always times of doubt from yourself and others, so reminding yourself it is real and had happened helps a lot.
Good luck, and I'm glad you are supporting your friend!
