Before you conclude that every dream is dealing with a weighty personal issue, take a look at what was going on around you, and in the world, the day or two before you had the dream.
The Dream: I'm living with other people in an apartment. The boy in the next room is playing a kind of music I don't like at ear-splitting volume. I'm very angry and go to his door, banging on it with a large pair of garden shears. It occurs to me that if he opens the door quickly I'll probably bang him with them.
At last he opens up, and I tell him how disturbing his music is, that not everyone has the same taste, and I suggest that he use ears buds. He agrees, and the music quiets down.
When I get back to my room I realize there is a window between our rooms. I can see him; he has no privacy. I wonder if he can see me, but then realize it's one-way glass. However, I think there might be another window that I'm not aware of through which another room looks into mine.
Interpretation: A few threads from the previous day's news and entertainment were woven together in this dream. Once I remembered them I marveled at the ability of the unconscious to make a narrative out of these diverse elements. I had the dream on a day when the Snowdon revelations of massive government snooping were being talked of everywhere. I had watched a video on how to use iPhone ear buds. I saw a mystery in which perps were being interviewed and observed through a one-way mirror. The mystery contained a knife attack (the shears) and banging on doors.
Did this dream have any deeper meaning for me? I'd say it pointed to some concerns, but that these concerns have more to do with our society than with my personal life. The issues of the dream are: privacy, peace and quiet, potential threats from strangers. The dream says that I don't like some of the things I'm hearing, and I'm angry about it. It tells me it's possible to cooperate with my neighbor, and that once I see into his world I have more sympathy for him. It seems we're all in the same boat.
