Although I have had limited (a few) telepathic and precognitive episodes, I do admit them. In 1982 I had a Grand Dream of and for my life. Some parts came true, like the Navy ship my Dad took me to. In the dream I saw an important person at a podium talking about the new ship.
Another, more subtle part of the dream there were holes in the clouds as I was passing through them in my dream. They were meant to be portals into another phase of my life. In "reality" I did see round holes in the clouds, but that's too subtle to verify anything. I did see a whirlwind with a rotating hole at the park where I was at.
Precognition: I am still looking for similarities with my dream. One of the images had a tall man with a bug flying around it...it's funny, because I have tiny moths flying around my home (they're harmless). No, I am less than 6 feet tall.
Just remember, synchronicity is very subtle and usually "insignificant" and require acute intuition to recognize them.
