is it bad that I have been craving salt?

like I just want to plain salt, anything with a salt taste I want it?

idk if that's bad or not?

like me and my husband ate popcorn yesterday and we have popcorn salt and all I could do is put my finger in the salt and lick it? it's so weird and I don't think it's safe to eat a lot of salt but I can't help but crave it!😩
