This happened about a week after my mom had died. She died June 25th of this year 2013. So this would be around the beginning week of July as I had taken 3 paid bereavement days and 2 unpaid days, which were my normal days off. I'm just trying to give you a time frame.
So, it's my first day back to work after my mom died. I was not expecting this as my mind was on the grief of my mom. No thought whatsoever pertaining to sightings or ghost stories. Part of the building I guard is now closed off to employees, the company moved the employees to the other side of the building to renovate the side that is now closed.
So I was patrolling this side of the building, the side being renovated, when out of nowhere I collided with someone. You know when someone rushes past you in a rush or in a hurry, and you and them collide side and arms together? That is what happened. I definitely felt the rush of air, the bumping of arms against each other, definitely solid contact there could not be mistaken, but there was no one in the physical body, but definitely physical contact!
So I swung around to see this person, quite surprised and most definitely intrigued. I have seen apparitions, but never felt one. He tried to manifest his appearance to me, but couldn't quite do so. I guess he didn't have enough strength to do so. What I did get to see though, was a man about 5 feet 6 inches or so, fat in the stomach, old blue jeans with suspenders, white t-shirt, baseball cap. He wasn't too clear or solid in his appearance. He was middle aged, 40 or 45. He appeared in a cloud of smoke. Anyone remember the kid from Charlie Brown, the one who always had a cloud of dust around him? That is how he appeared.
He gave me the impression he was agitated that I bumped into him, angry too, which is why he tried to manifest his appearance, even though he was the one in a rush. He tried so he could tell me a thing or two about bumping into him.
I was surprised and intrigued, but not scared.
