I have always had this gift, there was a large moment in my life where I kept it to myself after explaining to a very unbelieving 5th grade teacher that her mother is here, unknowing how recent she had just passed and how quiet the teacher kept the incident. She retired that year.
I have always seen glimpses into the realm we enter briefly after this life, and I have always been able to clearly tap into the worlds beyond that.
That's where I find my knowledge to help those who need that same knowledge.
