Sweet Mother,
At times I talk in my sleep. It is a sign that the mind lacks control, isn’t it? So what should I do to keep it quiet at night?
Generally when the body is asleep at night, the mind goes out because it is difficult for it to remain quiet for a long time; and that is why most people do not talk.
But your mind seems to remain in your body, so you must ask it to remain perfectly quiet and silent so that your body can rest properly. A little concentration for that, before going to sleep, will surely be effective.
Blessings.
