Not sure why this isn't brought up in other countries, but in the Philippines, when you dream about losing a single tooth, someone is surely to die. I believe this since it has happened to me like twice already, and I know a lot of people who can attest to this as well. This is pretty common knowledge in the Philippines and the dream that I fear of having the most.
Something bizarre and somehow funny that happened to me was when I dreamed that I was on a date with this pretty Jordanian girl from our office and we were kissing. On that same night my close buddy was dreaming that he was supposed to have a date with the same girl but the girl didn't show up.
It was a bit scary and i had to call the girl immediately after my buddy told me about it to make sure she was okay.
