Paranormal Activity?

 As I said before, I use to go to parks to walk with my boyfriend.  We started to visit those places since we started dating, and presently we like to go at least once in one or two weeks.  We like to release the stress from the whole week.  The day of halloween's eve we decided to go to the Cranbury Park, which is the one that we mostly visit. That day was still clear at 6:15, so we decided to take some photos to send home in our countries about autum and the amazing colors of this season.

While we were walking we heard something that passed behind of us, but even worst my boyfriend felt that someone touched him in his back. I thought he was jocking, but he was not.  We avoid the topic in that moment. When we got close to the castle, we noticed some "spots of light" on the photos although there were no lights toward that side; we were against of them. I tried some more photos, but only at the front of the castle we had this problem.

We started thinking in presences close to us after remember we heard about that before.  All this happened in almost 15 or 20 minutes, time very short for our regular walks, but we only wanted to leave the place at that moment. We could see that some of the spots look like they get closer in pics that are consecutives.

People that saw the photos later told us they feel something strange while they see the pics and that we shouldn't go there anymore at that time, suppously the time where the line of the paranormal world and our have a point of conection.  They also say that they can see faces on the spots that look to us. Well, if anyone think or know something about this, please I would be glad to hear about it....Is it or not paranormal? Who knows?
