magic or mundane?

Recently things have been going wrong more often than usual?! i’m in art school and am so meticulous with everything I do. a clay project of mine collapsed and i spilled a full jar of liquid wax everywhere. I’ve been wearing crystals forever, i can list my everyday ones if they’re relevant… but I got a new ring months ago. a malachite ring. when i wore it the first time i was dizzy but thought it was nothing. i’ve been wearing it this week and wondered why things were going wrong- last night i had a dream about it tarnishing and turning into a skull!!!!?!? i read it acts as like protection for evil eye…. maybe it’s tired LOL- idk if this is the place for crystal talk but 😟 i’ll take all the advice i can get.
