I had this dream a few years ago that I will never forget. The jist of it is this: I was on a small boat with some classmates, on like a field trip, and we were allowed to jump into the water and swim. While I was swimming, I went under water. While I was under, my back was facing the ground, like I was lying on my back under the water, and just swimming that way. I came to this little rock formation and started to swim through it on my back. I soon realized I was running out of air, and I couldn't get out from under the rock. When I ran out of breath I woke up, under my pillow!!! I don't know how I got under the pillow, and I guess that's what made me think I was running out of air, cause I was having a hard time breathing under the pillow. It was one of the strangest things. anyone expierience something like this before?
