I recall the first night of the second school semester last year, when I did something like that. It was a three-person room, and I was on the top bunk. I was having a dream that I was a cyborg cop or something like that, and I just got a signal saying that I was needed, so I threw the covers off me, jumped off the bed, and landed on the ground with an extremely loud thud. One of my roommates, without looking at me, asked what had happened. That was when I woke up and found myself back on the ground, standing in a really awesome pose. I told him that I fell out of bed, and so I just climbed back up.
I told both them them what really happened about a month later when it got brought up again, and we all had a really good laugh about it :laugh:
