Proprioception means “one’s own” or “ones’ individual” (Latin proprius) “perception.”
We normally use this word to refer to our physical position in the world—whether we are standing or sitting, how we are moving, and how much energy we are using.
When we dream, our capacity for physical movement, with rare exceptions, is paralyzed. But we still do a sort of proprioception in dreams—a semiotic proprioception, or proprioception within the semiology of the dream.
In dreams, we grope through semiotic associations and respond, gropingly, to them. People and things often look smaller in dreams, or distorted, because we do not have either the need or the capacity to calibrate our physical proprioception as we do in waking life.
Dreams move from one semiotic proprioception to another via our individual four-dimensional (3D plus time) groping/associative function. In one short segment of a dream we are at home, then we go through a door only to find ourselves on a boat in the ocean. Our 4D semiotic proprioception within dreams readily accepts groping, associative shifts like this.
Much of what we perceive when we are awake is memory. We glance at a room we know well and call up our memory of it rather than actually look closely at the room.
I am fairly sure that the memories we call up to aid perception while we are awake are much the same as the groping proprioception we experience in dreams. A major difference is when we are awake we can and do check our waking proprioception with the people and objects around us, while in dreams the associative function has a much freer range.
Notice how dreams move from scene to scene rather slowly. Things can go quickly, but normally dreams grope somewhat slowly along the 4D path of semiotic proprioception.
In waking life, our dreamy use of memory and association to aid perception of the world happens constantly.
When we speak with another person, we use this function to make groping associations concerning what we think they are saying. We grope and respond to them as in a dream while at the same time searching for clues that indicate we are both in the same dream.
These clues that two people may sort of “agree on” while speaking are normally standard public semiotics that belong to whatever culture(s) they share. By “agreeing” on them, we form a sort of agreeable camaraderie with whomever we are speaking, and this can be satisfying, but if we only get this, it can also become deeply unsatisfying.
The four dimensional groping/dreamy function of our mind is far richer than any standard collection of public semiotics. In our public lives—professional, commercial, based on organizations, etc.—we have, at present, little recourse but to accept normal public semiotics, to agree with them and manifest agreement.
We can express some deviation from them and sometimes make jokes about them, but we are generally fairly bound to the semiotics of the culture or organization that generates the context of our speaking. Consider how people in the same church or school are bound by the semiotics of those institutions.
In our intimate relations, however, we do have recourse to investigate and understand how our groping, 4D semiotic proprioception works. This is what FIML does. It allows partners to observe, analyze, and understand the semiotic proprioceptions of their minds as they are actually functioning during interpersonal communication.
If you constantly avoid FIML types of investigations, you will be stuck with a mix of dimly shared public/private semiotics that will tend to become highly ambiguous, even volatile, or very shallow.
