I was going to sleep last night and was enjoying a nice relaxed hypnogogic state as I drifted off. The blackness I saw behind my eyelids became a vast black space. And as happens often I enjoyed a nice show of vibrant colours washing around. The bit that has never happened before is then I heard morse code. But it was really fast. If I tried to concentrate on the beeps it would suddenly fade away. If I didn’t concentrate or listen for the morse code it returned. So there was no point trying to decipher it.
