Why NaOH is formed near the cathode in the electrolysis of brine?

During electrolysis of brine(aq. NaCl), NaCl and water are present as electrolyte.
Na+ (from NaCl) and H+(from water) tends to move to negative terminal (i.e cathode) while Cl- (from NaCl) and OH-(from water) tends to move to positive terminal(i.e anode).
Now only one from Na+ and H+ at cathode will get reduce which has higher standard reduction potential.

I didnt ask process of dissaassociation into ions. I knowafter reduction of cl- and h+ NaOH is formed but why it tends to go towards cathode?
U havent explained my question dude
