When I was in college, me and my project team mates used to go to this fabrication workshop for project work once per week. I was kind of a counter strike addict in those days. The workshop was inside an old building and at one particular spot, I used to feel like hiding behind the wall!
I guess it was more like, an impulse, not a conscious thought. So I had an impulse to do it, but never actually thought about doing it, and didn't realize what I had almost done until I was at a complete stop.
