I had this one a long time ago, but I still remember it. Here's how it goes:
it was night time and I was in my room when I heard a helicopter over my house. I went outside to see what was going on and saw the helicopter drop a crate in the driveway. The sides of the crate fell down and there was a robot alligator. It turned on and it's eyes were red. It then hissed at me, turned around then started crawling down the street. I got on my bike and chased it down the street. That's when I woke up.
Weird, eh?
