For example I think a lot, sometimes even longer that 8h in one piece and I do it usually after sun set or in darkened room.
Usually that thinking is about complex scientific and philosophical topics.
But when I do this I prefer to do it in darkness to prevent senses from slowing and destroying the process.
But catch is that somebody with time will enter the room. First they take a look in that dark room and then turn the light on. But only then they realize that someone is in the room and that someone is me giving them penetrating look which appeared out of nowhere for them. Because of this they can get a panic attack and they need about 30 seconds to calm down.
If I try to say something before they turn lights on the result will be the same because voice out of that darkness will scare them
Also what is confusing them is that I enjoy eating alone in atmosphere where you can barely see plate and fork. Sometimes if I have to eat in the light I just take my meal and eat it somewhere in the dark.
Probably most people are too S to understand this.
But generally all people dislike my ability to appear out of nowhere and they think that it is sick and totally creepy. Paranoid people have problem with this especially.
I remember that few years ago I scared one woman to death by accident.
I would say she was about 30 and probably some kind of an NF.
It was Christmas and it was night, somewhere around 8.00 PM and I was visiting grandfathers grave at local graveyard. When I was done I realized that weak moonlight and candles on some graves are creating wonderful atmosphere in this labyrinth graveyard so I decided to wonder around.
That was not my first time to do something like this.
Later I set my course towards the exit. But I ran into the probably only person on entire graveyard except me - women who is visiting grave.
I walk really fast (like other INTJs) plus graveyard is like labyrinth so from her perspective I appeared out of nowhere.
When she realized that she is not alone she freaked out and run away screaming.
Entire thing happened near exit so I run into her again when she was catching her breath beneath the street lamp. She said to me Damn it man you scared the crap out of me and when you did not start to run after me it was such a relief - LOL
After that we went separate ways.
Personally I really like to spend time alone in dark places.
It is the best atmosphere for abstract thinking and I somehow feel at home when I am in dark and quiet place.
Many people because of this say to me that I am total lunatic for doing this and living like this but to me this is one of the key parts of my personality and foundation of my success in life.
What I want to say is, if you have problem with people like me why do you have it?
This is not a joke.
