I went to a residential trip to the Isle of Wight in my primary school, there was one of the kids (I'll name him Alfie for this post) who had went to the toilet at around 11PM, he was above me on the bunk-bed in the dorm.
And the stupid things I do when I wake up... He had woken me up by getting out of bed, and I had thought to scare him, because it was really dark, so as soon as he closed the door in the toilet, I ran towards the wardrobe in my room, thinking I would hide in there and scare him.
But when I flung open the wardrobe doors and jumped in (I don't know why I had rushed it, probably because I had just woken up at 11PM and was hyper.), I had underestimated darkness, so the wardrobe then fell on me when I jumped in because I couldn't see where I was going. It didn't hurt really, there were 2 people who laughed in my dorm and I had shouted something like "it's not f****** funny!", because I was in shock because of a wardrobe falling on me.
After a minute or so laying there, now I recall of it this much, it actually seemed like I was under there forever. The teachers then came in and got the wardrobe up, I had then ruined the school trip for the rest of the people in my dorm, because afterwoods we weren't allowed in our rooms for free time because of what I did.
The rest of the time there sucked :/ But it is a laugh when things like your thread coming up, and me remembering what happened. Thanks for reminding me about it!
