Is the "roll over" signal real? Because, I don't know about anyone else but I've never felt it. And also I can't quite reach SP. My limbs feel heavy and everything but I can move if I try. Am I doing something wrong? I'm sure my physical body stays still, just my 'Astral' body (don't know if that's the correct term ) moving about a bit. None of the hypnogogic imagery comes on either after like, 2 hours. What am I doing wrong?
