While you are asleep, there may be things that you are doing you are not really aware of. One of them is talking in your sleep. We hear of this from people who often hear their partners murmuring or saying things while they are in their slumber state. It is not really a problem for most. Sleep talking, also know as Somniloquy, is termed as an inconsistent behavioral pattern possibly stemming from stress or some shortcomings that affect the psychological aspect gone unnoticed.
While there is nothing serious about it in the normal course of living, it still remains that sleep talking can be associated with some known sleep disorders. Remember, when you are asleep and dreaming, there are times you fall in that small gap of not knowing what to do. Psychological problems may be present but the thing is, it is better to consult sleep specialist before resorting to any means of trying to medicate something that may not be all that serious.
(Source) The cause of talking in sleep is not entirely known. Most of the time, the cause of this sleep behavior cannot be linked to any identifiable underlying problem or disease. And in most cases, the problem is not serious and tends to resolve over time or with aging.
However, in some cases, it has been found to be associated with other sleep-related disorders, such as sleep walking, REM behavior disorder (an unusual disorder in which individuals tend to act out their dreams while asleep), sleep-related epilepsy, post-traumatic stress disorder, sleep apnea, and the nighttime sleep eating syndrome. In addition, in adults who begin sleep talking in adulthood (in other words, they did not do this as a child), there may be a higher rate of psychiatric disorders.
