There's no indication that's what this is. I get that it's unintentional but by suggesting that it is the call of the void you might be doing a disservice to people who do experience this kind of intrusive thought.

I'm not an expert on this and maybe someone else can provide a more concise explanation but my understanding is, this is a french term "l'appel du vide" or something referring to the feeling you get standing next to a precipise something like "imagine if I just jumped off".

These are also called intrusive thoughts and other common ones are turning into oncoming traffic while driving or cutting yourself with a knife.

I think it's pretty common to experience them but they can be very unsettling if you're depressed, anxious, stressed, or in particular for people with OCD.

My limited understanding is, it's not your mind telling you "you should jump off" but rather, "be aware of this life threatening situation". It's like a vestigial life preservation system left over from a time when our brains were much less well developed.

It's important for people who suffer from these to understand that they're not harmful, and they're not at risk of one day being compelled to do something like that.
