ELI5: how exactly are we made of stardust

I get that all of the elements that make us are from stars but I just can’t wrap my head around how I am made of star dust… is this just a broader way of looking at the creation of elements in the periodic table or am I literally made of star dust. 
Sorry if this was a stupid question!

Update: 
OMG THANK YOU TO YOU ALL! 
I’m so glad that there are so many wonderful helpful people in this community!

Heavier elements like iron, calcium, nitrogen, etc only form in the pressure of a star. They are then flung across the universe when the star goes nova. The only reason there is iron in your blood or calcium in your bones is is because stars created them.
