Teeth falling Out in old High school Hallway Dream

"I was in my old high school hallway, but it was also my grandma's kitchen? The lockers were cabinets. I remember I was trying to tell someone something important, maybe about a test I hadn't studied for, and my tongue felt thick. Then I felt this weird popping sensation along my gums, like bubble wrap under the skin. I ran my tongue over my top teeth and they just... shifted. Not painful. That's the thing. It was more like when a loose baby tooth is ready and you can't stop wiggling it. I cupped my hand under my mouth out of instinct and the first one dropped out. Then another. Then three at once, clinking together like little pieces of chalk. I kept thinking "okay this is fine, I just need to find a mirror" but every time I opened a cabinet door it was another hallway. My mouth was filling up with this warm salty taste and I was trying so hard not to swallow because I knew I'd choke on them. At some point my sister was there? She was talking about something completely unrelated, like a parking ticket, and I'm standing there with a handful of teeth going "does this look normal to you" but my voice came out all mushy and she just nodded and kept talking about the parking ticket. I woke up literally drooling on my pillow with my jaw clenched so tight it ached. Took me a full minute to convince myself to run my tongue along my teeth. They were all there. Still felt wrong for hours though."
