My toilet dream is a bit like hereiam's. Back when I was young, I went to art school in Manhattan. I lived in the outer suburbs, so a long train ride was necessary. I used to use the ladies loo in Penn station...it was filthy but was less than sparkling clean. I started having dreams that I'd walk in and be faced with a long corridor to the loos...the floor would be ankle deep in water( or...?). Of course there was no way I could use it, but I seemed to think maybe, just maybe I could get through on tiptoes.
My other water dream involved ghouls, huge stepping stones, and more water...and darkness. I could feel myself trying to navigate from one stone to another...without falling in.
I have real issues with water...maybe because I never learned to swim. There were "classes" in HS...all us non swimmers left to our own devices at one end of a poorly lit pool. I couldn't wear my glasses...and felt totally disoriented.
And the flat I live in has been a nightmare of leaking taps...even after they've been replaced/fixed.
