Did not use the Neurophone at night but still couldn’t remember any dreams. Used the Neurophone the following night and remembered a dream. I guess the no-dream phenomena was coincidental.

I tried using the NEO sans SecretSound — no tapping sensation on the middle surface of the cranium. Then I tried just listening to SecretSound. I felt a slight buzzing in that area every once in a while. I then combined the two and the tapping recommenced. I increased the intensity and volume on the NEO and the tapping sensation became more pronounced. The rhythm did not follow that of the Neurophone or my heartbeat. Also when I switched the Neurophone to Orange mode (SecretSound still running) I did not experience the tapping sensation.

A friend of mine tried the NEO/SecretSound combo. He felt a strange sensation at his solar plexus. He then concentrated on his breath and fell asleep within minutes. Fascinating.
