2) One day in high school, for no apparent reason whatsoever, I informed a friend that I believed something bad was going to happen to their vehicle. Later that day, someone unknown to me (ie: not someone I might have “overheard” discussing this) broke into it and stole things.
3) In my 20s, driving at night with a friend along a highway that bordered a US army base, with giant evergreen trees along the boundary there, a flying object with dozens of lights appeared on the other side of the trees, matching my speed, and only slightly higher “altitude”. This went on for a minute or so. After we reached the destination, I began telling other friends about the weird encounter with a helicopter we had just had, and the friend with me looked at me like my brain had fallen out and exclaimed that was definitely not a helicopter. (The encounter was silent, and whatever it was flew at about 50 mph at 20-30 feet above ground, so he had a point, but I had fully bought into “it was a helicopter”.)
Could go on, but this seems a fine place to stop.
