Really? Wonder what? I had that one just once. I've had the underwater one several times.
Then, I've had one repeatedly about falling down stairs. I just go on and on down this endless flight of stairs. Weird.
Maybe something about the stress in our lives for the underwater. The nikkedness might be about fear of public speaking. Who knows - wish I could remember. I've been plagued with psychotic nightmares most of my life, but was doing ok until Darks crept in one night.
You don't even want to know how many cats we have :)
I've had repeat dreams of ghost towns, semi-abandoned gardens, houses on long hidden driveways, and empty fairground style booths.
Also had repeat dreams where everything is dark and backlit with a strange ethereal light, and everyone looks like ghosts.
