Question: Recently I woke up from a terrible nightmare in which something was strangling me. Why does this happen?Sri Chinmoy: While you are sleeping, if your two hands are joined together and are right on your chest, over the heart, you will sometimes get nightmares. Many times this happens. Also, it is not good to cover your face with the blankets and sheets.
