My sleep is not always sleep. I communicate and They communicate with me, because sometimes during the daytime, I had been too busy or was too busy. I don’t get Their message, so at night They beep me to remind me of these things. It actually sounds like when you’re beeping or the phone’s ringing or when you have SMS on your phone. It's not like that, but it has some sound. So that I notice. Sometimes it’s different sounds, different times. It depends on from which spiritual level, either from Shadow Universe or from the Original Universe. There are different sounds. And different departments.
