A Coincidence, or Psychic Message?

In the spring of 1975, my husband and I (just days into our marriage) went for a walk in the Arboretum in Ann Arbor, Michigan. It was a lovely spring morning, and we were enjoying our walk immensely. Suddenly, I fell to the ground, shaking so much that I could hardly speak. I am not an epileptic, nor was I sick that day. I continued to shake, and my husband Paul had to pick me up and carry me back to the car. He took me home, and laid me in bed, where I continued to shake for hours. There was no known physical cause. The next day, we got the phone call that my Mother and Grandmother had been killed in a car wreck around Austin, TX. They died instantly, at just the time that I fell to the ground shaking, in Ann Arbor, Michigan. I felt my Mom and Grandma leave this earth from 1500 miles away. The lesson I took from this was that we are all connected in ways we are not aware of consciously. But there must have been some communication, either body or spirit, that existed long enough to show me what happened, even if I could not put words to it. My Aunt Frances, now deceased, was driving at the time the wreck happened. Her daughter, my cousin Ginny, had tried to reach me for hours, but my phone was broken. When she finally reached me the next day, I asked her the time of the wreck, and yes, it was the exact time I fell to the ground in the Arboretum the previous day.
