When I checking the hot terminal in the socket, multimeter shows the current through me?
This is a really stupid thing to do.

You are measuring the difference in voltage between the mains and the ground through your body's capacitance.



You have not given a make and model of the multimeter or a link to its datasheet so it is not possible to construct an equivalent circuit. The problems are that you are using a meter for purposes other than which it was intended and you have no guarantee of safety. You are relying on current limiting due to the input input impedance of the meter and the very short clearances between the very many switch contacts - including those which select the mA ranges and these are typically fused (if at all) at 200 mA and this is more than enough to kill.
