An Apartment House & A Fictional New Season Of Luther & Alice Morgan?

I know that there was more to this dream but all that I can remember of this dream is that at some point in the dream I remember walking inside a windowless narrow somewhat dimly lit apartment house-like store, and the floor was carpeted/had carpet; and on the left side of the hall was a wooden rectangular table set up with my former male classmate EB and maybe my former female classmate DF behind the desk.

They seemed to be there either selling something and/or spreading the word about something and/or accepting donations and/or something like that, they recognized me and I recognized them, and we all smiled at each other and we greeted each other; and I kept walking as I talked to them as they continued sitting at their table.
