Help! I am worried about my friends.?

Today, I sat around the plaza of the university I attend, and when people looked at me I shouted, "I will cut your eyes out!!" After that got boring, I boarded the bus with my flippers and snorkeling goggles. People kept staring at me and when someone finally asked me why I told them that I was ready for the flood the aliens are bringing. I was made aware of this prophecy by the same person who helped me catch the elf trying to sell cookies to my neighbor. I think she is one of those Keebler cookie elves. Anyway, when I told my friends about this warning they didn't believe me. I am worried about them, that they will drown. How can I help them understand how serious this problem is?!?
