the 4th dimension is not necessary to be time.
there r 9 dimensions -length, breadth, height, time, mass, current, temperature, amount and luminous intensity. basically, there r 7. breadth and height r there just to give a 3 dimensional view. the 4th dimesion which some humans have can be any of the remaining 6 dimesions. these 7 dimesions r the fundamental or base quantities in physics.
a person having time as the 4th dimension can tell what will happen in the future. a person having temperature as the 4th dimension can tell where the temperature is hot or cold even with a slight variation in temperature.
as for having the 4th dimension of time, even i cm to have it as well as many of mypredictions come true
