The Eternal
I have a fear of hieghts as well. Falling dreams are the worst. Especially right before you hit the ground, you wake up stone cold with cold sweat all over you from the fear. It takes you a good 10 minutes to move again.
I have nightmares like that, except replace "about to hit the ground" with "about to be bitten by some sort of bug/snake/reptile/ect." gonk
