The argument from personal experience is an argument for God's existence on the basis of a personal religious experience.
An example: "Jesus appeared to me in a vision, thus I know the doctrine of Christianity is true."
Personal experiences are subjective, and are not evidence available to every person.
Personal experiences are used by believers of all religions, as well as believers in the paranormal and ghosts. It is thus impossible to tell if any religion is valid based on personal experience.
We know the the mechanics of the mind can mislead, and the intentional stance often leads people to see agency when there is none.
