There are those dreams that take the most recent thought or face and weaves them into your dreams. Sometimes, the heaviest thing one your mind continues to burden you as you sleep. However, the majority of faces are just random people who you will never meet, know or see again. Maybe deja vu is actually a face that appeared in a dream.
I don't spend much time trying to figure out what a dream means. More importantly I wonder, who are these people and have I seen them before?
Is it merely a coincidence when your alarm rings and a car in your dream honks the horn. So many sounds in our surroundings just melt seamlessly into our dreams. It's amazing the number of times the sound of the garbage truck has provided the ambient sound track for the gridlock in my slumber (that sentence just sounds like something out of a best selling novel).
Best of all, I love the dreams where I spend time with my mother. Since her passing, that's the only time we ever spend together... until we meet again :)
