Scary mold in potting soil

Good afternoon plant community! I've only been an indoor plant parent since January so forgive my ignorance. This is my second bag of potting soil bought from a local nursery. I stored it in this container so both bags were exposed to the same conditions. The only difference is on the second bag, I added cinnamon and perlite in the mix. I was going to repot my bromeliads this afternoon but as soon as I opened the container I saw this. I looked it up and people say it's normal, but the mold in pictures looked thin and thready. This one is a mountain and it looks crystallized. I'm currently drying it under this brutal Texas sun. Is this still safe to use indoors after it dries out? Thank you for the help!
