I've had some dreams like I was in a submarine and running to the next room when I hit the top of the small doors. And then I wake up and spring up into a kind of sitting position. I've also had times where I wake up strongly remembering something from my dream and looking for it. For example I once drempt that I had this amazing blue ribbon, why it was so intresting or why I cared about it so much I doubt I'll ever find out, but when I woke up I just kept grabbing at the covers trying to get the ribbon out of it. Then after a while I realised it was just striped white and blue covers. Or another time I kept looking for an iPod I got in my dream(tnhis was like two years ago when I didn't have an iPod and really wanted one so I spend about five minutes looking until I snapped out of it.
