Reoccurring dreams: I'm inside a building with wooden walls?

I want to be a physcologist and i have been studying dreams so I would say it could mean one of three things. It could mean your starting over and having a new start and thats why your the only one in the office.The elderly people could represent people who have passed away and are proud of your new start. It could also represent a new start and the elderly people are representing people who are no longer in your life and would like to be included in your new start. One or two people want to be in your life again.
