how do i cut off future contact in the after life and/or with reincarnation?

I want to find a way where I can if a specific soul, spirit show up again cut off future contact in the after life or reincarnation life/lives. How do one do that?

I'm afraid too because I've had a vision of us and I dont want it to come true.

When we met in real life (this life) we had opposite experience of that. This person said never forget it and how special that moment was. I did feel something strong going on but that was my shock over my disgust over this person. Usually I would say two people feel the same way when meeting eachother.
