ELI5: Why do humans get impulses to do things they know are incredibly stupid? (I.e. Standing on a cliff and having the impulse to jump off)

It's a mental phenomenon called "Call of the Void". 

Have you ever stood near an edge and considered jumping off?

Driving a car and imagining yourself crashing head first into a tree?

It's kind of your mind's way of doing things before you actually do them. It's a survival instinct we developed back then (imagining ourselves dying when we walk into a dark cave helps a bit).
