What is a one-sentence summary of the following article?
Typically you can remember only the last dream you had before waking. Don't move and don't do anything. Stay in the same position as the one in which you awoke and try to remember as much about your dream as possible before you think about anything else. Think it through from start to finish. While you're remembering, focus your gaze on the first object you see as you open your eyes. Look at the object; focus on it. That object will most often take the vague recollection of your dream to a place mark in memory where it is easier to recall details. A doorknob, a light bulb, or a nail in the wall, for example, will help you to settle into memories of what you had experienced while sleeping. Jot down as much as possible about your dream, starting with a basic sketch that includes such things as the location of the dream, the basic plot, the characters, the overall emotion of the dream (i.e. were you scared or happy in the dream?), and any prominent images you can recall. If you can't remember anything about your dream, write down the first thing that comes into your mind upon waking. It may be related to the dream in some way, and it might trigger recollections. Also write down how you're feeling when you wake up. The emotions you experience in a dream typically remain, at least for a brief period, when you awake, so if you wake up anxious or elated, ask yourself why. We have several REM cycles in the night, and they get longer and longer toward morning. If you only record the last dream you had before you get up in the morning, there are more dreams you might not be remembering. It's always tempting to go right back to sleep when you wake up in the middle of the night, but take the opportunity to remember what you were dreaming before you doin all likelihood you will not remember it in the morning. This is only recommended for people who get adequate sleep and who can fall back asleep easily. Otherwise, skip this step. Since you usually only remember the last dream you had, you can remember more dreams by waking up several times during the night. We go through a complete sleep cycle approximately every 90 minutes, so you may find it productive to set your alarm to wake you at some multiple of 90 minutes (such as 4.5, 6, or 7.5 hours) after you expect to go to sleep. Dreams in the later half of the night are typically longer than those you dream soon after going to sleep, so you probably want to wait until at least the 4.5 hour mark to intentionally wake yourself.
Concentrate on recalling your dream as soon as you wake up. Record your dream in your dream journal. Increase the number of dreams you can remember by waking up more often in the night.
