I had such a weird dream last night. What does the dream mean in an interpretation sense?

I think it means....you had to pee and your brain was trying to distract you from it so you didn't pee the bed. Police, color red, stop signs, barricades, and taboos in dreams are usually warning signs or barriers against involuntary nocturnal action (if you know what I mean). What you see in a dream is pointless. Why you see it is the important thing.
