I keep dreaming that I wake up, in darkness and cannot turn on any light. An I am then petrified and know something is in the darkness after me. Then tonight I dreamt of being in a dark room and all these dark monster like figures where trying to grab me and I was frantic screaming ‘ I am not afraid of you’ This is every night, the first hour I am asleep then I suddenly wake up from the dream. Anyone able to help?
