I have personal experience with both telepathy and precognition.
In the case of telepathy I have proven it to two other people. Of course that required telling them about their thoughts and experiences that they assumed were private. When the persons realized that their thoughts are not necessarily private it created some measure of trauma, and for that reason I wouldn't recommend doing this to people.
For whatever reason the telepathy has never happened in real time. That is to say the persons thoughts that become known to me are not happening at the time I become aware of those thoughts. It occurs spontaneously without will or warning. I have zero control over when it occurs, but it does occur, that's a fact.
