The entity I often sense hanging around in the upper level parking area downstairs in the building my wife and I live in appeared in the guise of a "shadow person," just after midnight today. While dropping off a big box to be recycled, I saw the profile of a completely blacked out, fully silhouetted figure moving extremely fast. It walked straight towards a wall and vanished just before it would have (had it been a living person) walked right into it.
There was no sound made by this thing whatsoever at all, and I only turned to catch a glimpse of it because I could feel (as I often do) that something was no more than three or so yards away. Maybe it was a prankster, or a shy neighborhood tenant darting in between the two rows of cars near the recycled goods? 100% doubtful. That close, moving that quickly, and this man sized figure made no sound at all?
Besides, when I was heading back toward the main lobby elevator, I paused by the guard office (where I could see the only guard on duty standing within) and stared for a long time at the spot where the figure had abruptly disappeared. Nothing there. Until... I realized it was still standing there. It was simply so transparent that if you didn't have a strong sixth sense, and didn't know where to look, you'd have completely missed it altogether.
So believe what you will. Or not. I've known about this particular shadow man for a long time. And he knows that I know about him, too.
