Being a Manhattan native I was trying not to make a big deal about the 10th anniversary of 9/11. It's always been really touchy for me and I usually don't like to think much about it, even on the anniversary that happens each year.
I was hungover that day (Sunday, 9/11/11), and completely wasn't wary of it over the night. I was just getting up, half-asleep at around 10 am when I felt a strong presence and could have sworn there was someone near my bed. I didn't see anybody physically, but I felt it through my closed eyes. All my roommates were out that weekend. It was a sensation that lasted about 10 seconds.
My apartment in Manhattan is not haunted and I've never had anything weird happen there. But after doing some research I found out there was a hotel there that was torn down in 2006. It's my personal theory that there might have been someone staying in the room of the hotel that my bedroom now occupies, who was somehow involved in 9/11 if not a victim. I believe the feeling happened at either 10:02 or 10:57 am, which were the times the two towers went down.
The rest of the day was pretty normal; just doing some work on the computer and watching the Giants/Redskins and Jets/Cowboys games. But whatever it was really moved me emotionally, and caused me to do a lot of reminiscing and Internet recollection about 9/11 the following week, which is a subject that I usually try to avoid. Our apartment is definitely not haunted, never any other feelings like this or weird dreams, noises, etc. But I really do think there was something there in my room that morning, and it might have been someone associated with 911.
