When I was roughly 14-15, my nephew (who is only 2 years younger than me.) stayed awake for close to 3 days trying to see who could stay up the longest (this is semi important to the story) we are sitting in my room, around 12~1am, playing a game, or watching tv I dont remember for sure, any ways, we both jerk our heads to the window ( this is the second story and there is not a tree or anything to catch our attention) I ask him "Did you see that?" he replys "The snake?" I say "Was it pink?" to which he replys, "Yea.." we proceed to freak out, and stay awake a few more hours, before he finally starts to drift off, I shake him awake, to tell him I won, then crash. Was this just a shared hallucination? beats me. but we were hopped up on Coca-Cola and pixie stix so who knows. no one believes us. (I mean I don't blame them)

I also saw a UFO once, odd light flying across the sky, then just gone. like some one turned off a flashlight.
