Teeth falling Out while Eating a changing Apple

"I was eating, I think it was an apple but it kept changing into other things every time I looked at it, and I bit down and felt this crunch that was wrong, not apple crunch, and my mouth just filled with these hard little pieces. spit them into my hand and it was teeth, whole chunks of them, jagged, way more than could've fit in my mouth to begin with, that part didn't bother me in the dream though, just the fact of it happening. kept running my tongue around checking what was left and finding more broken edges, sharp ones, cutting me a little, and there was this panic building but slow, not all at once, more like it kept catching up to me in waves. tried to talk to someone about it, I want to say it was my sister but the face wasn't really her, and my words came out mushy, couldn't form them right with my mouth all wrong, and she didn't seem to notice anything was even happening which made it worse somehow, like I was the only one in the wrong reality. went to look in a mirror and the mirror was in a bathroom that wasn't any bathroom I know, tile all cracked, and my reflection was a half second behind me, moving after I moved instead of with me. mouth full of gaps and blood I think but not dramatic blood, just present, just there. I remember trying to hold the broken pieces like maybe they could go back in, cupping them in my palm so scared to lose them, like that mattered more than anything else happening. then I was somewhere else, walking down a street, and my mouth felt fine again, tongue found all the teeth back in place, but I still had this leftover dread sitting in my stomach like my body hadn't caught up to the fact that it was over. never found out what happened to the pieces I was holding. just gone. woke up and checked my actual teeth with my finger before I even opened my eyes all the way."
