ELI5:Is quicksand actually dangerous?

Is it dangerous and impossible to get out of it you get caught in it? What causes it?

It's generally only dangerous if you're an idiot and panic.  You won't sink out of sight.  Quicksand itself doesn't kill you, the tide coming in, if it's on beach, or the sun setting and freezing to death, are the big killers when stuck in quick sand. 

Quick sand is saturated sand where the water can't escape.  You probably notice when you walk on wet sand at the beach it seems to suddenly go dry when you step on it because you're forcing out the water?  That doesn't happen with quicksand. 

It's usually quite easy to escape from too.  You just spread your weight out (lay down) and slowly make your way to the edge.
