Sounds to me like a mostly not seen before thing

> Is there a name

"False analogy" is what comes to my mind, maybe there's something better

I guess it depends on where you are, I live on the Mediterranean, where, if you panic in the water, you're just standing in calm water. I imagine the ocean is much scarier.

> maybe there's something better

I think we do need something better, I see it too often for it to not have an exact name.

Yes, in my case I was imagining a wide river close to a many millions people city, and people from the slums (no AC) go there to cool down, and more and more people arrive all the time to the river, pushing those already there outwards, deeper water, people cannot swim

At rock concerts 10 000 people can create dangerous pressure, I wonder if a deadly heat wave and the chance to cool down at a specific place can do that too

Or maybe people would spread out along the water, but at the same time, it might be hard for an individual person with occluded vision to know what makes sense to do

Sometimes people rush out from a building in panic, everyone gets stuck in the door opening
