We had (while growing up, driving age of course) many Instances of "Seeing" something. It was always something of our own making. Except for that time, posted about earlier.
The Only Other time I experienced "Something" was during my divorce. My Ex-wife had some friends that were into "Dark things". Was it only a dream, or did it happen, When I fought a "Demon". Nothing I could do did any good until "A Voice" told me how to vanquish it. I did as instructed, and told "Her and Her friends" (in my mind) they could not stand against the power residing within me, the power of light against their power of the dark. I was never bothered again.
