I blame a recent Amazing Race episode for the dream I had last night. I dreamt that I was swimming in a giant aquarium and sometimes on land. At first the manta ray was just gliding peacefully around the bottom of the tank and there were sharks too. (Seriously, this was a challenge on The Amazing Race which looked kick ass) but then I floundered around a bit and caught the ray's attention and it decided to attack me. It could change its size at will. AND It could fly out in the sky so it didn't matter that I kept getting out of the water. Here's the really interesting part to me according to dreammoods.com.
Manta Ray: To dream that you or someone is attacked by a school of manta rays, indicates that emotions that have been suppressed into your unconscious are becoming too overwhelming to keep inside any longer.
That's not at all disturbing.
