As the other guy said, you cannot have imaginary distances.

Incorrect. There are complex valued metric spaces

And even if we assume real valued metrics, then i usually represents the unit vector (0,1) which has distance real 1.

That's NOT a metric. That's a measure. Two wholly different things.

It can be a pseudometric

[-] stevedice@sh.itjust.works 1 points 3 weeks ago

That's more related to a metric but it still can't be complex valued and it's still not a measure.
