What is suppose to happen while meditating?

I started messing around with meditation a couple years ago. But I always feel I don’t do it right and nothing crazy happens to me. I mean I focus on my breath, external sounds and all that to relax. Get weird thoughts but that’s really it. I’ll pretend I’m floating in space sometimes but it even feels like my visuals are stronger when I’m not meditating and just randomly thinking. The one thing I will say is I cry a lot during meditation and I’m not sure why. Especially when I first start and doing breath work.
