I have this recurring dream about a swimming pool (sometimes inside sometimes outside) and noone else is around and I dread this dream every time I have it, but I know that I HAVE TO get in the pool and swim the edges of the entire pool not just swim back and forth the length of it.  There is a huge orca whale in the pool (and I know it's a male whale) and the water is really really deep and the whale is in the middle of the pool.  Once I get in and start my swim around the edges, the whale swims along side me under the water and I am just terrified.  I make it around the pool and the whale goes back to the middle and then I climb out of the water.  Only one time did the whale actually come up to me and bite my hand, but it was a nibbling kind of feeling, it wasn't as a chomp and there was no blood and I wasn't hurt or anything.  I really hate this dream and I've dreamt it on and off for years.
