Most dreams fade quickly after waking, which is why people remember so few of them.

The longer version

Recall depends on transferring a dream into longer-term memory, and the neurochemical conditions during sleep are poor for that transfer. Unless a sleeper wakes during or immediately after a dream and rehearses it, the trace decays quickly. Most people manage to recall a dream or two a week at best, despite having several each night.

Laboratory work found that awakenings from dream-filled stages produce detailed reports far more often than awakenings from other stages. Keeping a bedside notebook improves recall for some people, and the sheer number of dreams each night means most are lost. Interest in the subject during the day also matters, since people who think about dreams tend to remember more of them.
