I forgot almost all of my dreams from last night but I barely remember part of one dream, that took place in an unknown building were different people were going to party/eat/drink/relax with friends, and most groups of people were divided by gender and social group.

The dream followed four or more people, two or three men from a Navy / military group of men with mostly blond colored hair with whitish colored skin & light-colored eyes, and two or three women from a group of women who mostly had dark brownish colored skin with black colored hair & dark-colored eyes.
