Salty cravings

Normally before my period I’m on a sugar binge. I mean last month I got a huge brownie with hot fudge and ice cream (sounds gross atm) but now suddenly I’m 3 days away and I couldn’t care less about sweets, I’m craving all the salt. I just raided the kitchen for a few potato chips, and I added some extra salty sunflower seeds to my grilled chicken salad. My only other symptom is crazy weird and very vivid dreams. I haven’t had any of my typical PMS. Ugh! I’m so confused😞🤦‍♀️
