As mentioned in a previous thread, and something I often think about -
To all you ENTJs - how's your dark side?
Do you tend to see the dark side of things much? How much? How dark will you allow yourself to go?
Do you struggle with depression, and do things tend to get darker and darker during this time? If not, what does trigger it?
For myself, things can get pretty dark. I can have fiercely violent thoughts, the world tends to lose all color around me, and the combo of Te + Ni takes me even further into the depths of the ugly. I can see/hear something and my intuition will run with it. It's not pretty, and honestly, I probably couldn't write about some of the thoughts I have.
I don't stay in this place for long periods of time, but rather certain portions of a day, etc. I snap out of it. It's just when I go there, I go there intensely. For me, it also tends to directly correspond with loneliness and/or solitude. While at times it may be out of loneliness, other times it may simply be that I've been left alone in my head for too long.
And sometimes, I enjoy it. It's only once in a while that I creep myself out.
