Dreams are your subconscious mind trying to work through something or point out something. Usually, it is all symbolic. The key is to think about what the people, places, action, and objects mean to YOU. Don't take them literal, think more abstract.
Like your family members representing a feeling, or personality, points of view, etc.
What does a beer stein mean to you? An object someone else had growing up, a like or dislike of alcohol?
Apartment: 2 stories, layers, short-term issue?
Of course it can be more literal, been feeling powerless to relatives? Thinking someone in family could support you more?
The KEY is to step back and feel out your own symbolism about what it is about. But main thing to remember is it is just a dream.
