Chapter6 of the Wave (

To summarize, Ouspensky discusses the possibility that animals can only perceive surfaces and live in a 2-dimensional world. Since they cannot perceive or sense the third direction in space that humans are capable of perceiving, this third dimension appears to them as having a temporal character.
[quote author=Tertium Organum]
Animals see two dimensions. They constantly sense the third dimension but do not see it. They sense it as something transient, as we sense time.
The surfaces which animals see possess for them many strange properties; these are, first of all numerous and varied movements.
It has been said already that all illusory movements must be perfectly real for them. These movements seem real to us also, but we know them to be illusory, as for instance the turning round of a house as we drive past, the springing up of a tree from round the corner, the movement of the moon among the clouds and so on.
In addition, many other movements will exist for animals, which we do not suspect. Actually a great many objects, completely motionless for us — indeed all objects — must appear to animals as moving. And it is precisely in these movements that the third dimension of solids will be manifested for them, i.e. The third dimension of solids will appear to them as motion.

Extrapolating this hypothesis for us, humans, it would make sense that additional dimensions of space (beyond the 3) which we cannot sense will appear to take on a temporal character for us. If we are able to reach the state of perception where there is "no right and no left" in space, then "time" would very likely be different for us as well. If we consider the 3 spatial dimensions we can sense, even though we may not know exactly what lies in each of the dimensions in a certain area in space, we can choose to focus our awareness on it and find out. It seems similar to the analogy of power point presentation with slides and focusing on the particular slide to access the information at will. We cannot do this for what we call "time".
While we are in the state that we are, here is a model of time from Susie Vrobel's "Fractal Time" that I found interesting. In order to account for the internal (subjective) and external (clock ticks) perceptions of time, she models time with a "length" or succession, a depth or simultaneity, and a "density" in keeping with fractal dimensions.
Simultaneity indicates how many things are perceived by us to happen together. There are a number of experiments done to check the external time window within which sensory inputs coming at us is perceived as "simultaneous". Visual, auditory, tactile,olfactory - all these have different time thresholds. For example, within an interval of 20-30ms, visual impressions are regarded as simultaneous; tactile - roughly 10ms; auditory - about 6ms. Beyond these respective windows, the impressions will be perceived as successive. What we end up perceiving as "simultaneous" is a Gestalt; an integration of various sense impressions, thoughts and feelings. This is possible due to an integration of various inputs in a nested context. This Gestalt is our "now". How much our "now" can hold depends on many factors; after the "now" or simultaneity horizon expires, we move to the next or successive "now".
To take an example, when we are feeling bored in the "moment", subjective time seems to drag on. In this model, it would mean that the simultaneous/depth aspect of time is minimal, close to zero. The successive/length aspect of time goes forward. Our "now" is thin. On the other hand when we are engaged in stimulating interesting activity, subjective time seems to fly. The simultaneous/depth aspect of time here is more; more seems to happen and the "now" is thick in texture.
When we recollect events from the past, we focus more on the "thick nows" which seem to last longer in retrospect compared to the "thin nows". When trying to capture one "thick now" in language, we will probably write or say "
During this time, I saw... I heard ... I felt ... I thought ...". Authentic mystical insights often try to capture the content of experience of time composed of very thick nows - or even a single thick now with depth approaching a very high number (infinity in theory) - in book length descriptions.
