Is there a word for the following fear: being afraid of doing something you don't want to do and you know you shouldn't.
For example: if you're on a high place, you don't want to jump, but you're afraid that you'll randomly do it anyway. I have this feeling sometimes and I wonder if there's a name for this fear/phobia.

Those are called "intrusive thoughts" and are typical, but not exclusive, of Obsessive-Compulsive Disorder (OCD).
Edit: As I said before, intrusive thoughts are not exclusive of OCD. Many people do have them occasionally. The difference is that in OCD they are repetitive.
