I'll share a short tale of mine, I don't think I've ever been more scurred.
Basically I woke up in the middle of the night, and my cover is missing. I guessed it must have fallen down the side of the bed, so in the dark I stick my hand down the side of my bed, searching around becoming ever more frantic as its just not there. So I check the other side, nothing, so I have to turn on the lights, by now I'm really confused and scared someone is playing with me.
No freaking covers in my room at all. Door is closed as well. This is where I was really the most scared I have ever been, opening the door to see what the fuck is up. House is empty, I walk out into the corridor and am still terrified.
Walk up to the stairs and wtf, there is my doona cover, sitting on the freakin' bottom of the stairs.
Talk about anti-climactic!
