Dynamic Content - Change Content Automatically

Hi,
I read the Dynamic Content article but I’m unsure if it can do what I need. I’d like the content in a Collection to change automatically each time the site is loaded—showing a different collection every time. Is that possible?

(3 Columns, that can change every time the website gets refreshed for example)

Thanks!
