For me in a dream pretty much anything that holds water is a restroom. I don’t often dream about restrooms but when i do they are always in highly public areas and exposed on all sides, I remember once finding a small fountain in the middle of an open air market place and waking up before actually getting to use it, the idea I think is kinda like using a tree in RL, guess I am just not very picky and very confident in my dreams.
I generally wake up when searching for a bathroom in dreams.
that was a terrifying experience… I was going, and turned lucid, and just went, “uh oh, probably doing this in RL”
I wasn’t. Phew.
The last time I went to the bathroom in a dream, someone kept trying to barge in while I was going pee. Eventually I just blockaded the door and went. No pee in real life, so good times.
I tend to find that the restrooms in my dreams are huge and maze-like. Last night I dreamt of a recurring misplaced restroom in my school (it frequently pops up where the lost and found is meant to be) which was out of order, but I managed to find a properly placed one and actually use it (a rare occurrence, iirc), only to wake up half way through (thankfully dry IRL 
).
Bathrooms in my dreams are the exact opposite. They are usually tiny and full of lots of people. One time a bathroom actually had a TV in it. 
I dont remember of having dreaming of bathroom. Usually I pee everywhere I want … lol
dreams about bathroom were more nightmares to me.last time dreamin one were when i was 6,7years old.
I am home alone feeling strange.going to check the bathroom and see a cigaret burnout on the toilet seat.I flush it and get out of bathroom.suddenly everything around me starts shaking and i cannot open door from my apartment.then i open toilet door and see big black shapeless round and tall creature with red dot .boogie man from childhood it was.THE TOILET MONSTER buuuuuuu(ha ha ha.)
I only dreamt about bathroom visits twice(and in the same night at that), and they were…messy. 
i only remember one dream where i dreamt about bathrooms in particular. i was at this bar and i had ordered steak and eggs (not that i can get into bars, nor would i order steak and eggs). i went into the women’s washroom but all they had were urinals and i didn’t want to pee standing up so i just left.
I had a dream last night where I was in a toilet. The toilet itself wasnt strange at all but my chemistry teacher was there so it was a regular nightmare 
Toilet dreams, unfortunately, happen a lot for me. 90% of the time they are not only dirty, but completely public-- as in, all of the toilets just out in the open, no stalls, people showering nearby, no barriers except for the occasional wall to make it maze-like and confusing. o_0
Now that I look back on it- thats all correct. Public toilets are always dirty in my dreams OR there is some evil person/thing trying to kill me in the restroom. Weird x 1000. 
Funny! I can’t remember any toilet dreams. I’m sure I will have had them before though…
oh … I’ve just had a small fragment flashback of a dream I had last night …
there was an empty spot where the toilet was supposed to be!!
[color=darkblue]Was it a nightmare, where you needed the toilet?

Oh God… toilets in dreams are horrible for me. I remeber, one time I was trapped in this filthy, endless bathroom. The toilets werefilled with seweage 
, the tile on the floor kept on cracking (a recurring dreamsign from when I was a small child), and they never ended. I kept on walking for the rest of my dream, trying to get out without barfing.
One time I had a very weird dream, and the normal part was an outhouse that was compleatly filled with crap. 
I’ve been getting a few toilet dreams lately.
Always either in my old high school or one of the toilets at home.
They are usually fairly clean, although I remember once that I needed to go so badly that I pee’d in a pint glass… it over flowed 
I have had toilets in my dreams.
But they are always in places they shouldn’t be,
like in my closet, or in the middle of the livingroom.
I jump into toilets to get to different places when running away from the Green Goblin >_>
