Get electric shock when getting off from Stilo!!!!

Hello guys! I got another electric shock after I got out of the Stilo as usual and touched the painted door frame to the door. (not the plastic parts or rubber parts). That happens to 99 every time. I don’t know what that is. I’ve been doing it for a while. Do I get statically charged or do you know what it is? Is fortunate not a strong electric shock, rather when you try the basketball and touch the other (do you know it?) I hope)! Greetings
