The punctuation choice that effectively creates suspense and emphasizes a shift in thought is:

She stepped ... into the dimly lit room ... a room that seemed haunted ... and she ... shivered.

The ellipses create pauses that build suspense and highlight the character's shifting thoughts and emotions as she enters a foreboding space.
