Do recurring dreams have meaning?

I have dreams that aren't exactly recurring, but they have repetitive themes. Like i have a lot of zombie apocalypse dreams, but they're never the same. I also have dreams where my teeth with hurt A LOT and fall out (and it feels super real). Or another dream where I'll be trying to text someone (like a crush or a friend) something really important, but i keep pressing the wrong letters and i have to delete and start over until i get frustrated and give up. There's one where i finally end up with the person i love, but then halfway through the dream i look at them and they're totally a different person. I know the teeth dream is common, but i have no idea what the others mean. Wondering if anyone else has similar dreams?

Also, I had a really strange dream that i wanted to get my ears pierced with a second piercing (which is totally odd because for the longest time i decided i did NOT want to endure the pain of it). A while later, i was with my mom and she randomly asked me if i wanted to get my ears pierced. I asked how she knew and she said SHE had a dream about it! A couple of days later, i had it done. It has no real significance in my life, which is why it's such a weird thing to dream and prophesize.
