Are you high? Do you even know what the difference between communism and socialism is? Anyway, I'll explain:
Over a hundred years ago, there was this guy called Marx, who came up with a new idea of how to distribute wealth and power. He called his idea socialism, and the end state of his idea, or utopia, he called communism. Socialism was the strive towards the goal, communism was when the goal was achieved. 50 years later, there was this guy in Russia, called Lenin, who was a bit upset at his Tsar, so he decided to overthrow him and take power. Lenin was a socialist, and his revolution was a success. However, there were still a lot of people who disagreed with him, even though his revolution was the only successful one. Lenin was unhappy with that situation, as he wanted to spread his revolution to other countries. As a part of his propaganda, he changed the name of his party from the socialist party to the communist party, to "show the world" that he was no longer on the way to paradise(socialism), but was already there(communism). His followers around the world quickly did the same, and renamed themselves communists, while those who did not agree with them, retained the name socialist.
So, "communist" and "socialist" doesn't mean the same thing, a communist is a marxist-leninist, while a socialist is one who disagrees with Lenin, which means that they disagree with things like the dictatorship and the police state, and sometimes even the revolution itself, believing that the utopia is best achieved through steady reforms, not a quick revolution.
Saying that "socialism turns into communism", is really like saying that christians turn into mormons or something. Socialism is the whole, communism is just one brand of socialism, like mormonism is one brand of christianity.
As for Norway not being socialist, well, we've had a socialist prime minister for 75%(or so) of the time since the 30's, I'd say that makes us pretty socialist. Our brand of socialism isn't marxist-leninism, however, it's called "social democracy". And small state? What the hey? Our public sector is one of the biggest, if not the biggest in the western world.
