But faster than light time becomes imaginary

According to the formula for time dilation, the Lorentz factor

gamma = 1/sqrt(1 - v^2/c^2)

If v > c then we have in the denominator the square root of a negative number, hence gamma is imaginary.

Time won't flow backwards at all, but orthogonally, whatever that might imply.

Is there some reason that we are overlooking this factor?
