well, if you mean this really seriously and you are not kidding, then at first, skeletron is not summoned by entering the dungeon, the enemy that appears is the dungeon guardian. it is an almost invicible enemy that instantly spawns, when you enter the dungeon without defeating the skeletron. they both look similar, ut dungeon guardian appears only as a head without arms and kills instantly. the message "a horrible chill goes down your spine" is nothing to worry about. it mostly gives you some weapon (the musket or the ball o' hurt). the oneself message that can damage you anyhow is "the eater of worlds has awoken!". because you know the "terraria.wikia", then you should know something about this boss, if not, better browse the wikia.
