Perception of reality is dependent on perception of the fourth dimension, which is the dimension of time and space. Space is different than the third dimension of depth, because space describes change.
People who are not psychically conflicted can control the changing values of both time and space to suit their needs. Space is more important in times of introspection and focus or in self soothing, where time is more important during emergencies and when time is of the essence, obviously.
People who are psychotic invariably place priority on space, where people who are neurotic invariably place priority on time.
This is not to say people who are psychotic experience things in slow motion, as on some plane, slow motion is still time, as is a pause on reality. It is impossible to describe how time can be negated entirely because we live in the fourth dimension, so this quantum physical awareness cannot be understood. But it happens.
Psychotic people's negation of time creates thoughts which exist without any measurement of importance or priority, creating a world of ideas that, though prominent to the psychotic, would have most likely been idle thoughts if the individual's psychic senses were more balanced.
Likewise, neurotic individuals do not experience time in fast-forward, and their thoughts and perceptions are not actually ignorant of space. The dependence on time over space, however, creates thoughts that are evenly divided across time and only minimally capable of idea compression.
But then you have the borderline individuals who are neither completely dependent on time or space but who are also not able to control their focus of dimension. I think borderline personalities are prone to unpredictable starts and stops in their balance of time and space. Hysterical personalities, however, try to fit a lot of space in very little time. AsPD and NPD aren't borderline personalities. Dependent personalities try to fit a lot of time in very little space.
My friend wants me to mention that maybe no one's insane and we just shame other people's different ways of comprehending reality to comfort our secret awareness that we can't comprehend reality either. My friend literally was the one to say that, I'm not talking about a voice in my head or an imaginary person or anything. Jesus!
