The Former O'Keefe Centre - Toronto

I was just wondering if you have any information about the Sony Centre...formerly the Hummingbird. I work there in the condo sales centre for The L Tower and we have a storage room that I had to move items into one day in the summer. Every time I would go in there I got a horrible feeling out of no where. I don't know how else to describe it, but it was like a pressure in my chest and almost dizziness. It happens every time I open the door to go down the small hall way to get to the room and also while I'm inside it. I avoid it as much as possible and was just wondering if you've had anyone else ever comment about something creepy in the building in general.
