Fear is subjective, but The Twilight Zone Tower of Terror is widely considered one of the most intense "psychological" thrill rides at Disney. The "scare factor" comes from two distinct elements: the haunted atmosphere and the physical sensation of weightlessness. The pre-show and queue use eerie lighting and a creepy storyline to build high levels of anticipation. Physically, the ride does not just "drop" you; the elevator car is actually pulled down faster than the force of gravity, creating a "stomach-flipping" sensation as you lift off your seat. However, unlike outdoor drop towers where you can see the height, being enclosed in an elevator makes it feel less "vertigo-inducing" for those afraid of heights. If you enjoy the feeling of "airtime" on roller coasters, you will likely find it thrilling rather than terrifying, but for those who hate the sensation of falling, it is undeniably intense.
