i have had this dream more than once. im just in the bathroom in front of the mirror and i notice that my teeth are loose. I wiggle them with my tongue and can taste blood. i pull them out and spit them out and feel it. it's a weird sensation. Then i can feel those holes in my mouth and am bleeding and spitting a lot. in some dreams they crumble and fall out. in the last dream a couple nights ago two of my top molars were loose. i pulled one out and spit it in my hand and it was huge. like the size of big cow tooth. then i pulled out the other one and it was like attached to part of my jaw bone that i pulled out with it. i was freaking out. then when i wake up i think it was real and feel my teeth.
