Yes. I experienced this in Queenstown, NZ. I was on the outside edge of the building that’s up a hill, reached by cable car. Several of my fellow travellers were leaning over to peer down below, I tried but then had this involuntary urge, so backed away till I felt solid wall behind me and got back inside to the restaurant.
Thought it was just me.
(Managed to get some good photos though, one of which is on my FB profile).
Watch the video to get an idea of the view, and viewing platform. Oh, I loved riding the luge. That was great fun.
Apparently it is more prevalent than we imagine.
I still do not like heights but have never had my leg lift by itself since that time.
Guess where I was born?
Queenstown…Tasmania 
Not sure I would enjoy that. There are cases where cables have snapped.
Dozens of deaths over the years.
Same reason I will not take a helicopter flight.
I watched the video and it confirmed my thoughts. I would not enjoy that at all.
I experienced this during my first time at the top of a tower build during construction at the final floor level. It was a visit arranged as part of a lecture while I was attending uni. There was another who felt the same and our lecturer told us to see our GP’s before next attending. My GP referred me to some kind of shrink and after some exchanges of feelings and yet more exchanges, I felt far more confident. About 6months later while visiting another high-rise construction site, the little voice in my head telling me to jump never returned.
You were in a position where someone who knew about the phenomenon gave you sound advice. Very fortuitous.
I’ve never felt that I wanted to jump from a tall building but soon after my husband died I was driving and had a strong feeling that I wanted to drive into a brick wall - I didn’t of course but the compulsion to do so was very strong.
Simple,i don`t do heights.
That must have been amazing, what an experience, but I’m glad you resisted the urge to jump 
We went on an amazing one in Scotland
I love being up high with a great view but I’ve never had the urge to jump, it seems to be only train tracks and trains with me 
Yes, although I’ve never remotely felt the urge to jump there was something quite compelling and atmospheric about The London Underground. I remember the Bakerloo line in particular. The tracks would begin to rattle before you could hear the train approaching, next you’d feel and smell the blast of stale air as the train approached the station.
I had a friend who was a driver on the underground, he’d truly dread the prospect of a one under, as did his workmates.
Yep, a great ride and great views, love to do it again some day… 
The Christchurch one was great too, and twice as long as Queenstown.
Thanks. I’ve had a lot of thoughts in my life. Lucky that I haven’t acted on all of them. Wouldn’t mind some of them happening though.
Didn’t see one in Christchurch. We only had overnight stays there, beginning and end of the South Island tour, but the coach driver did take us on a drive round, showing the earthquake damage.
I’ve never minded taking cable car drives, so long as I’m fully enclosed. I adore being high up to see the views, of which Queenstown doesn’t disappoint.
Just looked at the website, Barry. Looks fab.
No I’ve never wanted to fling myself off anywhere.
Although I find the sea very hypnotic , sometimes I let the feeling of walking out into the deep wash over me.
I’m quite wary of heights.
Whenever I’m up high, I get the urge to back far away from the edge or to sit down on my bum - for some reason, I feel safer sitting down on a ledge than standing up!
I am drawn to Water, though.
When I’m standing at the water’s edge looking down at the sea or lake - or on a moving boat, looking at the wake of the water, I have to fight the urge to jump in.
I try to wait until the boat stops and drops anchor before I jump in for a swim!
I’m not sure if it’s an actually urge or if it’s just a feeling of tempting fate.
16 Montpelier Road?
There’s a story…or perhaps not.
