Why?

I was informed by my sister that I talk in my sleep, what's that all about.

Dear genius08

You will be quite relieved to know its a very common and harmless condition, requiring no treatment, unless associated with other sleep disorders.

"The medical term for this activity is "somniloquy." It occurs when you talk out-loud during sleep. A listener may or may not be able to understand what you are saying. Sleep talking can occur by itself. It may also be a feature of another sleep disorder, such as one of the following:

REM sleep behavior disorder (RBD)
Sleepwalking
Sleep terrors
Sleep related eating disorder (SRED) "http://www.sleepeducation.com/Disorder.aspx?id=16

"Somniloquy can also be triggered by stressful situations or occur in times of poor health. Stress and illness cause poor sleep cycles. A lack of proper sleep and eating near bedtime can also trigger sleep talking. To reduce sessions of somniloquy, take time to relax and de-stress each day. Make sure you are getting the proper amount of sleep you need each night."; http://www.happynews.com/living/sleep/talking-sleep.htm

Hope this helps.

Hi genious08, how are you? "Sleep talking may occur either during REM sleep (in which case the talk is clear and lucid) or, like sleep terrors and sleepwalking, during an incomplete arousal from delta sleep (in which case the talk sounds unintelligible, like gibberish). Sleep talking is usually harmless, although it may be disturbing to bed partners". Sleep talking may be caused by emotional stress, fever, or other sleep disorders, and it can often be lessened through good sleep hygiene and stress relief.
