In a mathmatical sense, yes. Here is a small example which I had conjured up which I assumed might be interesting to those reading my post: take two pieces of paper, and illustrate one geometrical structure on each piece (both being identical on each page). There, now you have parallel dimensions in geometry, existing within real time. As of today, there are a total of four known spatial dimensions, consisting of length, height, depth, and lastly; time.
.
time is not a spatial dimension. In the formula for the space-time interval in Special Relativity Theory, the time dimension has a different sign from the spatial dimensions. The usual signature is
+ + + - but sometime - - - + is used. The forth item in each signature pertains to time.
