Static Methods Preventing Usage Of Instances?

Declaring the method as static precludes one from using any sort of object oriented programming, thus the method cannot access instance fields of the object if it needs to.

I created two short classes to sort of find out what this meant, but I feel I do not understand it well enough.

Test class (main):

package votek; 
public class Test {
 public static void main(String[] args) {
SomeMethod();
}
 public static void SomeMethod() {
Character character = new Character();
character.totalLevel = 50;
 System.out.println(character.totalLevel);
} 
}

Character class:

package votek; 
public class Character {
private int level = 0;
 public Character() {
level = 50;
}
 }

OR

Does it mean that making a static method in the class with private instances will prevent the method from using the private instances?
