Dream of building, hands, person

I was walking barefoot in some slummy area of a big city with high rises all around me. The next moment I was in this building. I dreamed that I was in an opulent men's bathroom. It had beige-ish coloured marble floors and walls. Big mirrors all around. There were 7 basins. At each basin was a Jewish man. They were all dressed in black suites, white shirts, black hats and very bright blue shawls. Each basin had an arrangement of soaps and candles. All in white. I wanted to wash my hands in the 7th person's basin, but he refused. He told me to wash my hands in another big boxy basin. I refused. It appeared that they were preparing for some sort of ritual.
