Back up the ladder to the door room

Being in a room of giant ants is freaking you out. You don't have to make a conscious choice, your body is climbing up the ladder before you are even aware you have made a decision. Your hands are sweating and and shaking, which leads to near disaster. Half-way up, you lose your grip. As you slip down, you catch yourself, but not before your foot hits the rung below with a loud clang. You hang on the ladder, trying to breathe as quietly as possible when you are terrified. You have just convinced yourself that no one heard you when a clicking sound comes from below you on the ladder.

You scramble frantically at the rungs, taking them 2 at a time. The sound does not seem to get any closer or farther away. You practically erupt from the hole in the floor when you reach the top of the ladder and run without looking to the door right in front of you. You turn the knob in frantic haste. Just as the door swings open, you hear someone behind you yelling, "Wait!". You pause momentarily, should you turn around or run through the door to safety?
