No bathrooms for anyone

This dream had to do with an often reoccurring dream I have about toilets. I believe I was on a road trip with my grandmother.

We stopped either at a fancy rest stop or at a mall. I went searching for a bathroom and find one on a second or third level of some building.

There is a line all the way outside the bathroom and I think I'll never get to go.

For some reason, I determine that the line isn't for the bathroom, so I go inside. The bathroom is huge. People are everywhere. Most of the toilets are just out in the open like sinks. They are also fancy toilets that do everything from flush on their own to computerizing their problems to send for maintenance.

I look around for a free toilet and each one I find is either out of order or disgusting. I finally find one and the computerized part prints something out (each one had a printer attached to the wall). I don't know what it was.

I'm not sure I ever got to go to the bathroom.

Then I had to go home with grandma and clean up a mess she made in the bathroom.

I think there was also something about having to live with grandma and I just couldn't. I was going through the same things again as before when she got so sick I had to take care of her. It was like a flashback, but worse. Because in the dream, she was worse than before.
