Fear of heights...not too sure about that but I can feel my legs shaking a little when looking down from tall places. But I sat on a ride (with logs and water. Forgot the name of that ride) 3 times in a single day and an indoor roller coaster but it's dark inside, so I can't see the height but I can't see where I'm going...so I hit the sides and the safety handle whenever it turn too violently.
Oh I used to fear dentists as well...from a nasty childhood experience...until my dad forced me to visit one recently...and it's rather painless nowadays...
