I had a very eerie experience, once...
I had this dream where the ex-wife and I were still married. Some guy asked me "Do you love her?!". As I thought briefly...time had run out and I shouted "YES!" and I woke myself up cause I ended up saying it outloud!
That day, it ran through my head. I had an Aikido class that day cause it was a Friday; March 7th, 2003 to be exact, and I was going to head off to class soon after getting off work.
Earlier that morning, the wife said not to use the bicycle when it was raining, but because I got off work a little late, and it stopped raining, I decided to take the bicycle in order to make practice on time.
As I was going down this viaduct (under a bridge), a mom and her child were coming the other way, so I had to slow down. As I tried to speed up enough to get to the top, I got distracted, I swear I thought I saw a face staring at me...I didn't see the block of concrete that was being used as a divider to allow pedestrians and bicycles through the viaduct until it was too late and I side-swiped it with the bicycle. I tried to catch my balance, but fell hard on my shoulder with the first bounce, then my head with the second bounce.
That's the day I had severed my shoulder, and from that I had learned what kind of woman I had married...a year later I had divorced based on that experience.
Sadly, my shoulder is still unrepaired and four years later, I find out the ex had scammed the insurance claim from me.
That's about the "Ghostiest" I can get, cause the connection is baffling.
