sense of a dream

I am not a brain surgeon or a neurologist, but from what I understand, the subconcsious mind has alot to do with our concsious mind, and vice versa, and that our memories of physical and emotional experiences can be accessed easily by both concsious and subconscious. Dreams, the way that I percieve them, are made up of memories and extremely minute consciousness, so memories are played out on a seemingly concsious level. Dont look at the word Memories as full events, if u experience anything, it goes into memory, like the touch of grass or the smell or roses, you know, physical experience, and emotional experience is also stored in memory. As for such extreme dreams, very real fealings can become noticeable, and with some people, and myself, time seems to slow down for a brief moment in the dream. That aside, everyone who has ever driven a motor vehicle has some fear of a collision, and this fear may have surface in your dream. Dreams involving fear are quite common, so this is nothing to worry yourself over. Also, dreams are most vivid when you are more concsious during the dream than normal, so that is a major factor in the feeling of realism in the dream.
