Was I Too Tired Or Was It An Unknow Force?

I do not know if I can call this a Haunt or a trick. We went to an Asian festival last month during the last week of the summer holiday. We went to a location where they had what they call "Kimodameshi", translated as to test your courage. Basically, it was a "man-made" haunted place, where there will be people dressed in ghost costumes to scare you as you walk.

During that event my friend and his girlfriend paired up, I paired up with my sister. We let the couple go first then after a few minutes, it was our turn. We had to get a stamp from the fake shrine but before reaching to the shrine, we had to walk through part of a park and part of a cemetery.

Each of us was handed a hand written map, which basically tell us to go straight and never turn left or right during the way to the shrine. I thought it was easy we joked and fooled around as the "ghosts" came out and trick us. There was the last passage to the shrine where it is a part of a cemetery, I was told by one of the staff there that there will not be any "ghosts" during the last passage and that we will need to watch our steps and not to trip over by branches and stones, OK, I think at this point we can tell that the whole attraction was for kids.

Suddenly, my sister turned over and said that she could feel someone is following us, I told her that it could be one of the staff there either watching us to keep us safe or will scare us at the last moment, she laughed and let it be.

We could see the candle lights from the shrine we thought we were close by, but suddenly my sister stopped and told me that she did not want to head to the lights I told her that we are close and that there would not be any "ghosts" any more.

She pointed at the map and said we need to go straight, the moment I realize I was heading away from the passage in to a bush and I was right in front of a pond, went I looked again there were no lights at all. Could it be a hallucination?

We went back to the right track and headed to the shrine, sister was pulling me to go quick, while I was still wondering why I had headed to the pond.

Could I be having a hallucination or was it something paranormal? I have looked up the location of the cemetery and found no haunting cases there basically its European look and it is linked to the garden park nearby, quite peaceful during daytime and it will be closed during nights, they had open part of the cemetery just for the festival. There were lots of decorations at the park area but they did not put any decorations at the cemetery part to respect the resting souls (Asian thoughts?).

After we reached the shrine my friend and his girlfriend kept saying that they saw us walking around at the same spot over and over again they were calling me and my sister's name but we both were not listening, all the sudden I was heading towards the pond.

I got a little scared hearing that, we drank that night but it was after the festival, we were not drunk at all when we were at the attraction, some of the staff said they were worried because none of the people at the attraction that night had took time as long as me and my sister did.

Do I have to go to a doctor or is it paranormal activity?
