I hate heights as well!
One for me is an obscure game back on Windows 95 called Titanic: Adventure Out Of Time. It is a fantastic game but damn it is scary. I must have been around 7 or 8 when I was playing and goodness me, the dark corridors and spooky music, but most of all, it was the people you'd talk to that were scary, sometime they would randomly pop up...
Like this guy, Reverand Edgar Trout, this particular screenshot is from part of the game where your walking down a corridor and he randomly pops up and tells you about his wife who died doing charity work in India.
Just look at how creepy his eyes are!
