How to kill the vampires

When I was sleeping in the noon yesterday, I watched a nightmare. In the nightmare many zombies and Vampires attacked people in the town. And, I found the way how to kill the vampires. At the moment I woke up and write the way on my notebook in the real world before I forget it. I must do such a stupid, because I was sleep-fogged.
I photoed the memo. Now, I can't understand what is written. But, we can see human (or vampire) sleeping in the casket.
If such a accident happened in the future, this memo may help the Homo sapience.
