Why would a dream make sense?
This sort of idea does not violate and fundamental laws of Physics?
When we visualize “time going backwards”, we might imagine some part of the universe running in reverse, like an ice cube spontaneously forming out of a cool glass of water. But if the whole thing ran in reverse, it would be precisely the same as it appears now. It would be no different than running the universe forward in time, but choosing some perverse time coordinate that ran in the opposite direction.
Quote This sort of idea does not violate and fundamental laws of Physics?Perhaps not, but it violates our perception of reality, and any "rules" of experimental physics.There is a lot of "fairy-tale physics" involved in discussions about time reversal. Sean Carroll has some down-to earth things to say about it. For example: QuoteWhen we visualize “time going backwards”, we might imagine some part of the universe running in reverse, like an ice cube spontaneously forming out of a cool glass of water. But if the whole thing ran in reverse, it would be precisely the same as it appears now.

But he was going exponentially further and further from me in time and space?
Quote But he was going exponentially further and further from me in time and space? A major problem is that if you were travelling in opposite directions through time, in the same universe, you would meet only for a miniscule "instant", and never meet again.BTW, why would you see this progression as being exponential?
A very odd dream (but many dreams are). What did you eat the night before?Regardless of that, the principles involved in your dream are valid points for mathematical discussion. The phenomenon does not violate known laws of nature except for that of entropy. In essence, your entropy was running opposite to that of the other observer. In practice, no one to my knowledge has been able to accomplish this in the laboratory, but as a matter of theoretical discussion, it is worth discussing. (The phenomenon can be partially simulated by running a motion picture film backwards, but this simulation suffers from the deficiency that the person in the film is not actually present and observing you running backward in his reference frame). It would not seem, at first consideration, that an observer from one universe in which time is moving forward, is fundamentally precluded from somehow linking to another in an antiparallel universe where time is running backward. But then we try to do the physics of this and run into some problems, such as: Supposing that each observer simultaneously take a photo of the other. From the standpoint of Observer 1, the film in Observer 2's camera then becomes unexposed and erased, while that in his own camera remains good. Likewise for the way Observer 2 views Observer 1's film. But if these things are so, in what direction was the light traveling during the time of the photography? Observer 1 must conclude that light left Observer 2's camera at the time of photography (adjusted for the speed of light) , having been generated by Observer 2's film erasing itself through spontaneous reversal of its entropy. Likewise for Observer 2's assessment of Observer 1's film. In the case of your dream, the exact mechanism of observations was not, apparently, delved into. But it is worth, scientifically, asking the question: When you saw the other man and/or he saw you, light was going which way?
There is a saying that time flies when we are having fun. On the other hand, if you are waiting from the phone to ring, minutes can turn into in hours, in terms of our perception. The dream could represent a contrast between things you enjoy and obligations that are not enjoyable. On the one hand, you move ahead when you do the things you like, and on the other hand, things you don't like, make it appear you are falling behind.In terms of physics, consciousness can tweak our perception of reality, where perception of time, speeds up or slows down relative to the clock; standard time. In the fight or flight mode, time can slow so much, what are normally rapid events to fast to notice, slow like for Nero in the Matrix. It is not clear how consciousness is wired into time and space, since it is the reference by which we perceive time, with this reference able to alter perception of time.
In the "Family Guy" cartoon series that is often on the TV there is an episode where time runs backwards (Stewie very nearly gets unborn) had you perhaps watched this or left a TV running ?
