You can feel event interference when you have some future event that you have planned. There are universes where you go to or experience the event and those universes where you don’t. As the time for the event approaches, you can feel the probability that you will go to or experience the event change. One moment you will feel like it and another you won’t. When there are roughly equal number of universes where the event happens and where it doesn’t, the feeling of “will I go” vs. “will I not go” will alternate often.
