non-lucid

I think there were a lot of things on this dream, but I remember just one scene:
I was inside a small, square-shaped cyan room, and one wall was replaces by a giant fish tank. There was a giant pipe incrusted in a corner and some fish laying in the floor.

It was creepy, but the thing has turned creepier when the blue one flew into me (I'm sure there wasn't water) and tried to kiss me. I slapped the fish, but he returned and I slapped it again.
That blue fish was quite strange. It looks like a regal tang-colored angel fish.

Well, what do you think it means?
